Articles: Electrical & Wiring

Member-submitted articles related to DSM electrical and wiring.
This article was well researched and written because I could not find any tech articles on how to install aftermarket guage lights on a 2g using the factory dimmer switch. The majority I found are 1g articles and the installation process is a bit different. This article will explain how to wire your aftermarket guage lights using the factory dimmer switch in detail with pictures on a 1998 Eclipse GST.Assuming you have already installed your aftermarket guages (boost, air fuel ratio, exhaust temp., ect) I will go on from that step. However, this article was written installing two Autometer Ultra-Lite boost and exhaust temp. guages on a 98 GST. Certain guages may have different light set ups and may vary on how much of a charge they...
Here's yet another way to rewire your fuel pump. I like this method because you can just grab a relay from a junked DSM and it'll snap right into your factory setup for a nice clean install. It keeps all your fuses together and it also puts the ground wire under the dash so it is easy to install a hidden fuel pump kill switch within reach of the driver. It's also dirt cheap to do. The only thing I bought was a length of 12ga wire. I already had everything else lying around the garage thanks to a spare toasted wiring harness and some junkyard relays I had.1. If you pull the knee guard on 1g's (not sure on 2g's) there are a few empty sockets where relays can go. You'll be using one of these as well as an empty fuse holder under the...
Take all the bolts off holding this piece of plastic on their should be 3 or 4 bolts. Carefully unclip all the sensors in the area after (4 fuel injectors - cam angle sensor - TPS - coil pack - transistor -thermostat housing (3) sensors be careful on these cause they are brittle also the ISC - O2 sensor - throttle plate sensor (remove the fuel rail bolts 1 by 1 to remove the cruise control cable and get it out of you way its a pain in the ass, l tuck it back out of the way.Here's the wire bracket off. Take our flat head and pry out on the tabs careful in case you want to use this piece again.Here's the firewall the harness runs along the wall with bolt brackets you can remove with zip ties holding them to it. Trace it all the way...
This is fairly short and simple. For wiring up your non-turbo 1G 4G63 to accomodate turbo injectors, you will first need to purchase a stock injector resistor pack. These usually go for $5-20CDN, depending on who you buy from.This is simple and is the most common cause of consern for turbo n/t-ers. They just don't like working with wiring.1. Open up the wire harness that runs to each injector. You will find 2 wires going to the plug on the injector. 2. Cut all the thick yellow wires running to EACH injector. 3. Take the white wire from the injector pack and connect it to just one of the wires you just cut. Make sure it is the one that runs to the car, not to the injector. The other 3 harness wires running to the car should be...
I'm new to writing tech articles, so I'll give this one my best shot. Mods: I'm not sure if this goes in the body mods forum, move it if you'd like). Onto the good stuff...Things you'll need:- Two 2'x4' boards of 3/4" MDF (Medium Density Fiberboard). You can use 5/8" too, but you might as well use the thicker density. Plus, the dimensions for this box come out perfect for the JL sub I was putting in.- Cheap carpet from home depot. I bought a 4'x6' sheet for $6. I only covered the top portion of the box, but I had enough left over to cover it all.- Elmers wood glue.- Silicone sealant (in the caulking bottle) as well as a caulking gun.- Staple Gun with staples.- Drill with 1 small bit and phillips head.- A...
The below diagram and installation procedures were pulled from ECMLink's NLTS installation article but broken down a bit more, so people like me can understand them. If you haven't seen the ECMLink NLTS procedures just follow the link ---> 2g Clutch Wire Instructions If you still have questions and want more detailed pictures follow along and this article will take you through the install from start to finish. After I finish up with the installation instructions I will also talk about setting up your NLTS feature in ECMLink V3. *NOTE*: Use this 2g ECU pin out to refer to ALL wiring concerning the ECU harness. ---> 2g ECU pin out Edit Note: The wire cut/splice at the ECU in steps 7 & 13-16 can be eliminated by depinning pin...
This article will contain how to rewire your alternator and install a Farad capacitor to your amp/audio system. I used a Sosche Amp wiring kit that comes with the capacitor from walmart for $80, so it worked great.Lets start off with the materials you will need to do this: Approximately 6 ft. of 4-Gauge wire (6x) 4-Gauge Ring terminal crimps(Ace hardware carries these) 4-Gauge and 8-gauge or similar diameter shrink tubing A Battery terminal that has more "ports"(optional but recommended) Wiring loom protector A farad capacitor if you choose to do so(Highly recommended!) Zip ties Electrical tapeYou will also need basic hand tools, primarily a 10mm socket + ratchet, a wire crimping tool, screw driver, etc.So first disconnect your...
This should be exactly the same as a 1g, if it is not please let me know the difference, as there is no REAL write up on how to do a battery relocation, I figured I'd help some guys out!There is my diagram I made.I don't mention Circuit breakers in this write up because I am not using them YET. You should use circuit breakers to protect the battery though, it's a VERY good idea.You must buy as much wire as your car/tuck/needs so I will not give you any steady numbers, but it's a lot of wiring and a lot of money. It is NOT, repeat NOT cheap to do this, so if you're doing it for the cool factor, exit this page now or just go ahead and hack it together and start your harness on fire.Overview:This is the proper way to...
This article is to cover the major points in installing an EGT gauge on your 1g dsm. The 2g dsm installation is the exact same.If you want to install an EGT chances are that you already know what it does and different people want it for different reasons. I got this gauge mainly because I just installed a new motor and ecu and since I didn't have a datalogger at the time I invested in this setup. As we all know this is a very economical setup to make sure you are not running too hot internally.I got this setup for a very nice price ...the list of parts is below:*autometer lite 'pyrometer' gauge *autometer 2 gauge a-pillar pod *TRE EGT probe *Electrical wire (i forget what gauge wire i used) *and of course very important...
Original information found here: http://www.angelfire.com/fl5/import/germantail.htmlOne of the steps found there was not needed, and some of the instructions were a little confusing so I modified it a bit while everything is still fresh in my mind.Parts needed: 2 8-ohm, 20-watt resistors from Radio Shack(Part #: 271-120) Some spare wire, you may want to pick up a roll of speaker wire at Radio Shack Wire cutters and strippers 10mm deep socket Flathead and Philipshead screwdriversNow, on to the fun:The amber-cornered European/Japanese taillights will work with the American version of the 2G Eclipse as long as you make some modifications to the wiring. Hopefully you have access to instructions on removing your...
Apexi AVCR Install in 1g ------------------------This install really isn't that difficult if you feel ok with tapping wires at your ECU, and in my opinion the hardest part is getting that horribly designed wiring harness threw the firewall. If you have not yet looked at the AVCR kit you've purchased now would be a good time.1. First off you need to find a place where you want to mount the AVCR display/control in your car. Several members of the forum make mounting brackets/kits that will allow you to mount them in several places. I simply put mine by the stereo and did a custom job.2. While you're playing with the cars interior it's time to pull out the stereo and side panels so you can get to the ECU's wiring. You're going...
I decided to wire my parking lights with my turn signals. if you look at the plug its a 3 wire plug with only 2 wires. and it takes a dual filament bulb. everything is there you need to do this all you have to do is finish the connection. Things i used to do this: Butt connectors Wire with pins Wire cutters/ pliers basic tools to take lights off (screw driver) 1st thing i did was of course disassemble the lights. 1. take out 2 screws holding in center part. 2. i flipped up the lights 3. then took out the two screws holding in the turn signals 4. take out the bulbs 5. take out screws holding in parking lights 6. take out bulbs 7. then unplug the bulb socket from the connector. 8. get some wire and wire pins any small gauge will work...
ok the pictures are going to be posted in order...so when you see Picture 1...that is picture one and 2 is next one uploaded...here ya go...did it tonightHave a general idea of where you are going to place the unit…..I am putting it on my steering column on top of my turbo timerFirst off you need to find a place to pull all your hoses and connectors through. I found that he steering column boot works well. PICTURE 1You need to tee the boost pressure host for the unit fromt the fuel pressure solenoid which is here ( PICTURE2 So it looks like this PICTURE3 Then run the hose through the firewall to the back of the unit and don’t forget the filter included. This is how I put my boost controller...
So the Spidey write up was missing parts to get your signals to work properly. Most people who attempted the wiring came out with hyper blink. I have resolved this issue and also provided pictures. Lets get to it!Tools: Two 8-Ohm 20 what resistors Radio Shack PN: 271-0120 Solder Soldering iron Wire strippers/cutters Electrical tape 20' of Auto wire 10mm deep socket Regular screwdriver Phillips Screwdriver Volt Meter Awl/small pointy objectHopefully you have access to instructions on removing your taillights, but in case you don't, I've included a brief description of the tools and process. A 10mm deep socket will come in handy here. Remove the two panels for bulb access. Also take out the center section of the interior section of...
This applies only for 2Gs (1995-1999). If you are installing an aftermarket alarm and/or remote starter this should help you out. This should also help out those installing turbo timers. There are various diagrams available online, but a lot of them seem to be wrong, and most if not all are very vague. For a lot of us who like to do things ourselves it makes things difficult. So finally here is a more detailed and hopefully more accurate diagram for us. Enjoy!If you want to use your turbo timer with your aftermarket alarm, please read my entry on that here: http://www.dsmtuners.com/forums/articles-electrical-wiring/332597-wiring-aftermarket-alarm-turbo-timer-together-easy-way-no-cutting-relays.html**Always verify the wire by probing...
The A/F gauge, or "light show" like many of us like to call it could be accurate enough to have an idea of how rich/lean you are running your engine, although its not accurate enough to rely on it. Its been proven that there's nothing better than a WideBand O2 sensor, but if you did just like me and bought one of these autometer gauges this article tells you exactly how it works.Oxygen Sensors All oxygen sensors must be heated to at least 600° F before an accurate signal is produced. This is why when you first start your vehicle the signal climbs up slowly until it reaches operating temperature, and afterwards keeps bouncing from side to side.When the engine is at heavy load the monitor should indicate rich. At cruising load...
Okay here is my understanding, and what worked for me.The gear selector is still connected to the neutral saftey switch (grey thing on left) Their is no modification needed for that.From the NSS, i will solder the diodes directly to the new wires going directly to the solenoids in the transmission in the order the picture shows. In doing so i will add 2 wires in the cab for a switch to activate 4th gear, which will only work if the selector is already in 3rd.also my 2g wire colors are different, from the NSS on the 1g the colors i have are.1.big red. blue stripe -not needed 2.big black. white stripe - not needed 3.yellow. red stripe -goes to solenoids 4.yellow - goes to solenoids 5.yellow. black stripe - goes...
Discussion thread here : http://www.dsmtuners.com/forums/newbie-forum/410779-90-model-dead-tach.htmlThis fix has worked for several vehicles now but I must say that there is no way to know what kind of side effects this may have. I've talked to one person who's had this for 2 years, but he is the only one I know of. If you use this fix and you have issues afterwards, then post up here please. -------------------------------------------------So today Sep 19th, 2011, I have found what I've needed to know for many many days.

So I recently had my nearly new 17 month old oem 75 amp alternator go funny on me and it was time for this GALANT swap so I ordered a unit from the UK only to find out that the UK Galant is different then the US Galant!Im doing this because I could not find a part number to work with to help me search and it WILL save time in the future for others! so this should help people when they need to do this swap!this here is a UK Galant alternator matched down to the correct year and from the same engine 4g63 vr4 but this is 100 amps and I even tried the 90 amp 2.4 unit aswell but that was the same style aswell,this is the link Mitsubishi Galant VI | 100 Amp ALTERNATOR | 2.0 16V (A1939) - The Starter Motor & Alternator Company...
Eclipse to Talon Tail Light Wiring ConversionFor the longest time, I've wanted to convert my Eclipse's tail light wiring to function like the Talon's where the brake and blinker lights are completely separate from each other. If you do this with a hard top Eclipse, it could be as simple as swapping a section of the harness, and the blinker relay. However, for the Spyder, that isn't possible (without major splicing of the two different harnesses). This setup can still be done, as many members on this forum have done it, but I haven't seen any write-ups. With help from 97eclipseNT, I have completed the wiring modification, and the tail lights operate the way I want them to. I give him credit for the info I'm providing, but I'm just the...
Air/Fuel gauge Connection1. Remove the driver's side access panel from the center console. There is one Phillips screw and one push-in plastic screw that holds the access panel on.2. There are four plastic connectors plugged into the ECU, directing a myriad of wires going to and returning from the control sensors and relays. Connector 1 has 26 terminals, connector 2 has 16 terminals, connector 3 has 12 terminals, and connector 4 has 22 terminals. The terminal numbers are shown below. (Look at the ECU with your head under the steering column, with your left ear pointing to the floor. The connectors are from left to right, connectors 1, 2, 3, and 4.)2G Turbo DSM ECU Terminal NumbersConnector 1 1 2 3 4 5 6 7 8 9 10 11 12...
So how do you keep your spark plug wires separated after upgrading to larger than stock spark plug wires that don't fit into the stock black plastic divider?Well, I have a cheap solution for you.Here are a couple of pics that are worth maybe $1 – $2 in zip ties.This part only pertains to Tuners that have DSMLink installed. I just finished installing DSMLink, and since I have a 97’-99’ Eclipse GSX, it is required to switch the spark plug wires around at the coil. After I switched the spark plug wires around, I was anxious to get her fired up, so I kinda hurried when doing this simple little mod. Remember, cars with stock spark plug wire routing are gonna look a little different, but you can still use this mod to keep...
Not enough space in your favorite car's engine bay? Do you really not like that eye-sore of a battery next to your 4g63? Not wanting to add hundreds of dollars in breakers and inline fuses?Well utilizing the stock fused components you still can toss your battery in the trunk or behind the passenger seat.What you'll need:-25 dollar 4 terminal distribution busbar with plastic cover (TSIAWD666 uses one also) ~readily available on ebay-2 Gauge wire for extending the positive post connection (7 to 8 feet to reach behind seat, roughly double it to place the battery in the trunk) ~[2 dollars a foot] I went to Advance Auto for all the wires-4 Gauge wire to ground the negative (2 gauge works as well but not necessary) ~[Most likely...
