Have you tested anything yet? You connected to just the driver door unlock, not the all door... so the other doors won't unlock. In order to use the progressive lock, you will need to connect the aux/trunk wire to the all door unlock and the blue/black to the driver door unlock. Then make sure to change the programming options to set the aux for 2nd unlock.

Also make sure that both the Violet and Violet/Black wires are grounded to a solid chassis ground.

Excuse the laziness for me to read all 27 pages of this thread and now reviving it after 2 months, but I can't seem to find an answer to my problem

I drive a 2000 2.5rs and I'm installing a compustar alarm that does not have a neutral sensing wire. I want to utilize the hoodpin idea (with a diode towards the ECU of course) but also want to keep a functional hoodpin switch as well. Is there a way to wire this up in series so I have both the neutral and hood closed conditions in place when I want to remote start?

Hoodpin input is a negative trigger
NPS throws +12 when in neutral

The NSS will either be a ground when in gear or a ground when in neutral. You can only use the hood pin idea IF it is a ground when in gear (which it sounds like yours is). No matter how you wire it, if you leave the car in gear, the unit will think they hood is open... regardless of how you have it connected (diodes, etc). As long as you don't leave it in gear, the hood pin will always remain active for security. As far as remote starting, whether it is in gear or the hood is open, it will think that the hood is open and not allow the vehicle to remote start.

And it never hurts to test it periodically to make sure your safety switch hasn't gone bad.

Thanks Klarowe!

To be completely clear, before I accidentally fry my ECU:
tap into the NPS wire at the ECU, 1 amp Diode towards the ECU, then tap that wire into the wire coming from the hoodpin which leads into the alarm brain?

Sorry if I'm being extra redundant

You won't fry your ecu unless you tap into the wrong wire. A diode is simple an electronic 'check valve' that will only let current flow in one direction. So if you connect it backwards, all it will do is not give you the signal you want (which you would soon learn once you tested it). Make sure to test with a DMM before making ANY connections. And once done, sit in the car, put it in gear (with your foot near the brake pedal in case) and try remote starting it. Make sure that the unit does not allow it to remote start.

Your compustar may not have a neutral wire, but it should have a wire for the e-brake and that can be used to connect to your neutral safety wire. The neutral safety wire should read as a ground while in neutral and 12v+ in any other gear.

Not too sure about the other models but the GC8 only thows 5V in gear, which means it's not enough to throw a standard car relay.

I'm currently still trouble shooting it, and I can't cant's seem to find the right wiring strategy to make this all work in unison. I tapped into the wire at the main harness that leads out of the ECU.

1. I tested it, it throws +5V when in gear, 0 when not
2. Ran it directly into the hoodpin input instant trigger and the car still started in gear
3. Ran it directly into the brake input instant trigger and the car still started in gear

I might have a faulty brain?

Edit:
Shouldn't be a faulty brain because hoodpin and brake inputs work. Maybe 5V isn't enough?

You may not have a neutral safety wire in your '00'. Many cars didn't have one back then. You need a wire that reads ground while in neutral. Compustars are designed to do manual mode without that wire.

Your compustar should have a manual mode. You have to connect your ebrake wire and have your clutch bypassed to have it work properly. You just have to enter manual mode before exiting the vehicle. Sometimes you just have to throw on the towel and use what is proven to work.

Is there a neutral safety for my car? can you show me how it works? Im using viper 5704. what color is the wire coming from the dei unit and where do i plug it? do you have pictures? i have another thread on this, but the more info i can get the better.

I had given you pretty accurate instructions on your other post. Message me if you need more info. I will try to find pics, but there really isn't a lot to see.

Wanted to chime in with a question before proceeding- I have recently won a Compustar CS-700AS. This is just set up for autos, and I have a manual '05 Saabaru. The thing is that this unit does not have a specific e-brake or neutral/gear sensing input, and I can only hook up the hood pin to set off the alarm, not to disable remote start. My thought for safety is this: the + input detection wire from the brake pedal immediately kills the remote start. I'm thinking I will run the + Neutral(in gear) indicator from the ECU to the same input on my Compustar, and isolate both inputs with diodes to prevent feedback. I apologize if this in the thread somewhere, I've read about half and haven't seen this issue mentioned, and hope I've brought up something new since this is a newer unit.

^^Found the answer to my question on page 15 where it suggested doing EXACTLY what I figured would be the best hookup with my system. Thanks to all that contributed to this thread, feeling far more confident about this install.

Edit: Just went back and read page 15 that says it will work that way. Make sure to test it multiple times though to be sure it functions correctly. Some units require a certain 'level' of input in order to trigger the shut down... and going that route may not work properly.

I pulled some wires again to double-check my safety wiring which did not seem to work. After fixing a couple shorts and bad diode placement on my part, it appears that running the brake signal to the + remote start shutdown wire on my Compustar will not work, but the green/black wire on the ECU both kills the running car and prevents remote start if the car is in gear, so I do have a working (and simple) safety built in finally. The brake kill is nice, but I'm far more concerned about thievery or starting in gear, and recommend any other Compustar owners look at that as well if they drive a manual.

The brake shut down is another safety feature and should be used. You need to find the wire that shows + when the brake pedal is pressed. Then use that wire and the green/black ECU wire together (diode isolated) on the + brake input shutdown of the remote start unit.

I could dig back into it and retest the wire, but I'm not too worried on the safety side. Seems like more of an anti-theft feature than anything, and in a theft the car would go into gear (and most likely have a foot on the brake anyway). Unless I'm missing something?

As long as it shuts off in gear, then it's not as bad. The key is to make sure that the unit shuts off before you are driving. Otherwise if something happened inside the ignition switch to where the key was not actually running the vehicle (still under remote start) and the remote start timed out, the car would just shut off on you. If you were on a highway or something, that could lead to an accident. The other issue is that Compustar units require the brake signal input in order to learn the tach signal. How did you do that if you didn't have it connected?

Mine came in tachless mode by default, so I haven't set up the tach yet (but plan to). When I recheck my brake wiring, I'll repost if I confirm the signal not registering on the Compustar.

Take note of exactly how you have it connected (brake switch, neutral safety switch, diodes, and compustar unit). Also make sure to connect tach or you will end up having false starts in the cold weather.

Default Transponder Bypass help

Has anyone used the iDatalink AL CA in an 06 STI. I found the wiring for it one night, and now that I have the module, it doesn't exist for my car. This is the last thing that I have to wire up, and I'd much rather not button the car back up, just to undo everything to use a wire from my 5704. Also, if anyone is in the Jax, FL area, with an iDatalink item and also owns the iDatalink USB, would mind helping me finish the programming once I get the module wired up, if it ever happens. Thanks.

Just having the USB cable will not help. Only authorized dealers can access the flashing options. If you send me your email, I can send you the install guide... but it is available on their website (listed as just an Impreza, not WRX). FYI, do not use D2D with the 5704. The DEI units have been known to have data issues so the safest and best way to install is to use the hardwired method.
