1995 Eclipse wiring information

I have had a couple of requests for a wire sheet on the '95 Eclipse, so here it is:

12v: white positive at ignition harness
ignition: black/white positive at ignition harness
accessory: blue/black positive at ignition harness
starter: black/red positive at ignition harness
tach: blue/black AC at coil pack (2cyl signal)
lock: brown/white negative at relays in center console
unlock: brown negative at relays in center console
doorpin: red/green negative at courtesy light under dash
trunkpin: red/green negative in driver's kick panel
factory arm: green/yellow negative in driver's kick panel
factory disarm: green/white negative in driver's kick panel
brakeswitch: green positive at switch above brake pedal
parking lights: green/white positive in driver's kick panel
hand brake: yellow/black negative at handbrake or behind instument cluster
horn: green/red negative at steering column
driver window up: green/red reverse polaritiy at main window switch
driver window down: green/blue reverse polarity at main window switch
passenger window up: brown/yellow reverse polarity at main window switch
passenger window down: green/yellow reverse polarity at main window switch
headlights: red negative at light switch harness
reverse lights: red/blue positive in driver's kick panel
dimmer: green/white positive at dimmer switch harness
key sense: green positive at ignition harness

Be sure to use a computer safe test light, and TEST each wire to be sure it's the correct one; and that the polarity is right. I take no responsibilty for any incorrect information and/or faulty wiring done by any installer, but this is the latest information my program supplies. Good luck, take your time, and have fun!

You know what, this is such damn good information I'm gonna bump this thread up for no other reason.

Another great reminder why people should SEARCH this board, a lot of great info !

I will check this against my 1998 soon, see what is the same and what is different.

Good post, thanks !

The differences on the 1998 Eclipse are minimal, but consist of:

tach: AC on the 2.0 non turbo engine, tach is brown or brown/blue at coil on top of the engine(2 cyl. signal) or white at pin 73 of the PCM on the left side of the engine compartment. On both the 2.0L turbo and the 2.4L engines, the tach is white at the power transistor on top of the engine.

hoodpin: blue/black at junction/fuseblock above driver kick panel

driver window down: green/black reverse polarity at main window switch

The rest is identical.

You must be the GREAT GOD who has fallen from the skies! Yesterday, I was trying to find the meanings of the colors for the igntion harness; today, I bump into this thread, and every single detail I need to get my used HKS Type IV timer installed, it's all here!!! Thanks for the info.

I don't see a listing for the Ignition2 wire (powers radiator fans and HVAC). Here are the wire colors for the 2G key switch:

WHITE (Constant +12V)
BLUE/BLACK (Accessory)
BLACK/WHITE (IGN1)
BLUE (IGN2)
BLACK/RED (Starter)

Looks like everything else is correct, but you need to know IGN2 so you can install a turbo timer correctly... turbo timer outputs should go to IGN1 and IGN2 circuits.

Now it's even making more sense. I guess I have to get under the dash one more time. I got the damn thing to work, but my radiator fan would shut off when the key is taken out. PEACE!!
PS: Thanks James92TSi...This site is OFF DA HOOK!!

It is almost identical. Give me your year, and I'll give you the differences.

Thanks James! My program shows some differences, so I will list what I have. Be sure to test with a computer safe test light, everybody.

My program does not list '90 Eclipse, but this is for a '90 Talon:

12v: white positive at ignition harness
ignition: black/white positive at ignition harness
accessory: blue/black positive at ignition harness
starter: black/red positive at ignition harness
tach: white at front of engine
lock: brown/white negative left of steering column
unlock: brown negative left of steering column
doorpin: red/green negative at courtesy light under dash
trunkpin: red/green negative in driver's kick panel
factory arm: green/yellow negative in driver's kick panel
factory disarm: green/white negative in driver's kick panel
brakeswitch: green positive at switch above brake pedal
parking lights: green/white positive at fusepanel
hand brake: yellow/black negative at handbrake or behind instument cluster
horn: green/red or green/black negative at steering column
driver window up: green/red reverse polaritiy at main window switch
driver window down: green/blue reverse polarity at main window switch
passenger window up: green/yellow reverse polarity at main window switch
passenger window down: brown/yellow reverse polarity at main window switch
headlights: red negative at light switch harness
reverse lights: red/blue positive in driver's kick panel
dimmer: green/white positive at dimmer switch harness
key sense: green/yellow negative at ignition harness

Yo alanseijas, can you check and see on your program if a 90 talon is any different than a 92 talon. :hail: thanks
The only difference is the location of the tach wire on the '91 and '92 Talon. It is listed as being at coil on engine.

Actually I screwed up and just pulled that out of the database without proof-reading it. There was one listing for 90-92 Talon, which is what I gave. There is a mistake on the ignition switch harness on both Alan's and my charts. We went through the same issue when we posted the 2G charts... doh! :D The mistake is on the ignition switch wiring:

- The blue/black wire is Ignition 2 (power to HVAC and radiator fans), not Accessory.

- Accessory (radio, rear defrost, wipers) is solid blue.

So the correct ignition switch wiring is:

Constant 12V+: White
Starter: Black/Yellow
Ignition: Black/White
Ignition2: Blue/Black
Accessory: Blue

That is verified on my car (I went back and looked at my notes from when I did my alarm). Also note that sometimes they used a solid black wire for +12v constant instead of solid white. I've seen it both ways on 1Gs, so be aware (this is why you test your wires before installing).

For RPM signal, the database said white at the coil, but you can pull RPM signal from Pin 21 of the ECU much more easily. I changed it on my chart since I had DSM-specific knowledge. I'm not sure about the RPM wire under the hood on 90s, but on 91-94 (and 2Gs too) RPM is the white wire at the ignition power transistor (under the intake manifold, driver side). I'd rather get the RPM signal from the ECU than under the hood though, since it's one less wire to put through the firewall.

There are 3 plugs on the ECU (small, medium, large). Pin 21 is on the large plug, bottom row, 4th pin from the right. It will be pin 21 for all 1Gs, including 90.

ECU pinout: http://www.vfaq.com/mods/ecu-harness-1G.html

And like Alan pointed out, always verify your wires with a computer-safe test light or multimeter before installing. There are a few differences between our charts because there's more than one way to get to these wires. Use your judgement to figure out which way works best for your install, and test your wires before installing.

see above post regarding 90-93's, they are completely identical on the stereos

And yes I realize some of this is redundant from the 90-93 but there was no simple way of putting them in one post w/o seeming rather confusing and looking quite sloppy
