Default 02-05 impreza/wrx remote start/alarm wiring..

Im bored, so Ill post these.. Yes, they are accurate, this is the same wiring I used to do my alarm/Remstart... remember to always use a DVOM!!!

[Wire/Function] [Color] [Location] [Polarity]
[12VDC ] White 4-pin blue plug at steering column* +

[Ignition] Green 4-pin blue plug at steering column* +

[Accessory] Yellow 4-pin blue plug at steering column* +

[Starter] white/black 4-pin blue plug at steering column* +

[Tach Signal] blue/white In brown plug behind battery** AC

[Lock] red/white In white 20-pin plug at Body ECU*** -

[Unlock] yellow/red In white 20-pin plug at Body ECU*** -

[Doorpins] yellow In 16 Pin connector at Keyless module**** -

[trunk Pin] yellow/red In 16 Pin connector at Keyless module**** -

[Brakeswitch] white/black At switch above brake pedal +

[Parklights] orange In main black harness at steering column***** +

[Hand Brake] pink Below Handbrake in center console -

[Horn] green/red In black 5-pin plug at steering column -

[Clutch Switch] green/yellow at connector above clutch pedal type 2

* - The wires change color on one side of this connector, verify both sides

** - Provides a 2 cyl signal

*** - the Body ECU is located on the left side of the steering column

**** - the keyless entry unit is found under the driver's side dash directly above the fusepanel.

***** - You must test this wire with ignition turned on

Also, heres a little trick if you want to do remote start in a manual vehicle. Most all DEI remote starts have a blue wire called status output. This wire sends a ground before remote start engages. If you take this wire, and hook a diode up to it with the stripe pointing towards the unit, then take the other side and hook it up to the clutch wire (above) the vehicle will remote start. The diode tricks the ECM into thinking that the clutch is depressed. This way, you dont have to unplug your clutch wire and have no cruise control. A downside is that you can accidentally start the car in gear, but I put my remote start in a while ago and I've never done it, so be careful. Another cool thing about having remote start is that most all of the new ones come with a programmable turbo timer that is already hooked up when you wire the unit up. Theres a lot of cool things you can do if you understand wiring and polarity. Any questions, you can PM me... Enjoy!

The 04 Sti has a neutral safety, as do quite a few other models, but I don't know which cars. The info is here somewhere.

In the 04 Sti, two harnesses come up the driver's side of the tranny, cross over the tranny, under the TMIC, then go into the firewall. One harness only has three wires. That's for reverse lights. The other has about 5 wires. Two of them are green with a black stripe. One of those wires will show a ground when the transmission is not in neutral. So using a ground active defeat wire, like the hood pin input to a DEI rem-start, you can avoid having the car lurch if you forgot and left it in gear.

If you have an under hood light, as I do, diode isolate it or your underhood light might be on whenever you are in gear, or worse, will source too much current and let out precious ECU smoke.

Also, the handbrake wire is integrated with the DCCD on the 6 speeds, and has some odd pause (or did with my setup) when used as a remote start disable. I didn't feel comfortable using it after a while, that's why I finally hunted down the neutral switch.

FYI...

1. Hand-brake is a light green wire (not sure where you got pink from) on my '04 WRX. It can also be found in the passenger kick panel (which is a little easier to get to than directly under the switch at the handle).

2. Instead of splitting up the wires between the keyless/BCM/ign harness, you can find the horn, lock/unlock, door triggers and trunk pin all at the keyless module. This saves on effort and time. For '04+ you can also get the turn signals at the keyless module (if you want them to flash like OEM on lock/unlock), but for '02-'03 you still have to go to the ign harness for that in particular.

3. The tach signal is available behind the gage cluster and also at the ECU, so that you don't have to go into the engine compartment for it. One less wire you have to feed thru a grommet...

I harp about this all the time, but I get annoyed when other people seem to fail to appreciate that:

You will void the manufacturer's warranty and (depending on your jurisdiction) break the law by installing a non-M/T remote starter in a M/T vehicle!

Frankly, with the variety of R/S systems out there today, I can't imagine why anyone (in GENERAL, I'm not trying to point fingers here) would continue to promote the practice of using A/T-only remote starters in M/T vehicles. Using the status output of a R/S unit to by-pass the clutch is perfectly acceptable, just as using the NPS is, but not when the alarm brain isn't configured for safe starting. Check out Clifford, Autopage and Ultrastart if this is something you're interested in...I'm not sure about Compustar, but for sure Viper doesn't support it. Hopefully with DEI running the show now everything will standardize and there will continue to be more variety of appropriate choices...

'Cuz Viper stuff works. Component failure rate on their stuff has got to be a fraction of those other brands. I wouldn't chock a wheel with a Clifford. I'd install Alpine in a pinch.

But I thankfully don't have to worry about it anymore. No more installing for dill-snip, button pushing, whiney little customers anymore. Just my own cars and those I choose to work on. I do it right and answer to no one. DAMN that feels good!

yes, im very aware that it is illegal. Im just posting a way to make a M/T car work with an ordinary remote start system and not one made specifically for M/T cars. And ya, my 02 wrx has a neutral safety switch by the shifter in the center console, i didnt post it because i forgot what color it was. STi's and others have them too i presume, right? Voiding warranty? No, nobody on this board would want to do that...nobody...

ya, i knew hand brake was light green, i dont know why i wrote pink.. i think i had a brain fart...i had white castle earlier. I know that you can get tach from behind the cluster and all the wires at the keyless module but all these wire colors is what I had written down from my last install. I wouldnt have remembered all the "easier" ways unless I looked under the dash. Wow, Imprezas are so easy to work on

i have an auto 96 L, would the wire colors be the same? i had a chart and it said that the tach wire is black and blue at the ecu but i checked all these and my remote start still doesnt work. it turns but it doesnt stay on. should i just tap into the engine bay?
