01 A4 Compustar Install

[Gregor2004ua]

I just bought a two way compustar alarm with a remote start, has anyone done something similar b4? Any wiring diagrams for the install will be appreiated.

[Dallas09]

Yeah ive done it with Viper on my pre 99 A4 (meaning it doesnt have chips in the keys, which im almost postitive you do, so ull need a bypass kit for that). So to get to the ignition wires, i hadta take the airbag and steering wheel off, the lower kick panel and the insturment cluster. Most of the wires are behind the insturment cluster but some have similar colors (thin blue wire) so its possible to do it all without taking the steering wheel off but its not a good idea. I would test the wires with a multimeter between the ignition and where i wanted to actually tap them and you cant test the wires at the ignition without taking the wheel off. Tracking the wires down would be difficult since there are like three wrapped harnesses behind the insturment cluster. Lock, unlock, i got in the trunk at the central locking unit and ran them up front. Get the wiring info from the12volt.com If u want me to post some pics let me know.

[zrowcool]

nah no chip in the key, the b5 didnt come with an immobilizer for which would used the chipped key

[Dallas09]

Perfect, it isnt really that hard then. The one thing i forgot to add, is there is one ignition wire i didnt tap up there, it was the yellow and black one, i tapped that at the 75x terminal. But yeah, let me kno if u need help with it or pics.

yeah, pictures will be very helpful.
what do they mean by the parking lights, which lights are those, and where can i tap into them.
and it also has a wire to power up the AC system, i guess i dont need to do that, because when the car starts up the AC goes on itself, its climate control.
for the door locks i can tap into the wires in the door panel. does it also arm the alarm or to that i have to go to the alarm module. and where is the alarm module located.


the 12volt website doesnt have the diagrams or wire color codes for 2001 :(

[Dallas09]

I believe its possible to find the arm/disarm wires in the door panel.. Im just not sure where they were and the wiring info i got said at the alarm module. I do know that the wires you tap at the alarm module are the trigger wires for the door lock cylinder (its hard to explain, but I can tell by the way the car acts when i lock the doors with the remote start, the lights dont flash, only the horn honks, and its responsive when the car is on). The alarm module is located in the back right side of the trunk under the floor.. if you push lock or unlock and get near your trunk you will hear the vaccumm turn on (since the locks are controlled by air, not a solenoid). If you tapped the lock unlock wires for the rocker switch on the door, this wouldnt help you since the alarm will still be armed.

Parking lights are the orange ones in the front and your tail lights. The advantage to wiring these is they will flash with the alarm, or turn on when you start the car.. But they have to be diode isolated (research on 12volt.com if you dont know what that means). You dont need that A/C wire, you just have to leave the climate control on when you turn the car off.

http://www.the12volt.com/installbay/...518~PN~0~TPN~2 It was on the 4DR sedan part a couple pages in. It says your alarm module is under the drivers seat, ive never heard of that before so id check on that.. It also talks about the thin blue wire causing problems and its listed as a start wire and ignition wire, ull hafta ask in the forum on that one becuase my blue wire was only an igniton, making it much easier. They list all of the wires accesible at the fuse block, except that blue wire so ull hafta pull your steering column apart anyway it looks like.

12volt claims theres a transponder in the key... so idk if it were me id check by wrapping the remote completly in tin foil, becuase i believe the transponder would be at the tip of the remote. If your car didnt start then it would have a chip.

This job looks a little tougher than mine with that goofy blue wire and the possibility of a transponder... Mine took me a good two days id say, since I had never done it before. If you have never done any 12volt wiring before this would be a terrible idea to try and do just for caution and to scare you even further i attached a picture of what the steering column looks like. If you plan on doing it i can give you more step by step but this is basically the only picture I got, the others just show closeups of the same thing.

Finally, I also used wiretaps, they work good for now but they arent the greatest idea for a remote start. The wires dont draw too much current, but they arent the most reliable. If you plan to do soldered connections, add quite a bit of more time to the processs, the soldering process takes a while, but the big problem is getting enough access to the tight and short wiring harnesses, theres just no slack to work with..

only the euro models got immobilizers iirc

[Gregor2004ua]

Thanks for the link to 12volt, i didnt notice the chart there, i thought the page was only on stereo system.
I hope it doesnt have the imobilizer thing, ill be testing it sometime soon.
the chart explains everything pretty well, ill be doing the project sometime during the week, so ill keep u guys posted.
thanks a lot for your help. might need some more later :)

[Dallas09]

Sounds good keep me posted.. as long as u got that blue wire figured out and u check all the connections as u go along u should be good to go..

[Gregor2004ua]

I ran into a problem. I cant find the hood trigger wire, trunk, and doors.
how exactly do you find it ?
and also what is a glow plug wire?

[Poopie]

glow plug wire is for diesels

[AP-Specialties]

If anyone is interested, we are having a group buy on Compustar Remote starters right now through the 12th. PM me for details.

Should be in one of the harnesses at the central locking unit with those wire colors, otherwise you can find them at each door switch.

[Gregor2004ua]

Ok i located the wires at the alarm module under the back seat. now i cant figure out which wire is for which door or trunk. there is about 16 wires. 8 of them show 0.00 reading when the doors are closed, when i open one foor ALL of them read 0.07v. and the color codes at the 12volt site are not correct i guess, because there are no wires with the colors said in the diagram.
im pretty sure im at the right place, because when i disconnect the wiring from the module the alarm doesnt arm anymore when arming it with remote, but the doors lock anyway.

[gotdubd]

they should read anywhere from 7-12volts when closed and 0 volts when opened

i dont mean to insult, but being a mobile electronics installer myself. this is a job you may want to leave to a professional.

and i promise you, programming all of your options will be much easier with a Compustar programmer instead of through the book

edit: on my b5 i got my door locks and door triggers coming out of the door boot into the car.
and the factory alarm arms/disarms with lock and unlock

but there should be a separate wire for each door, hood, and trunk door, right?
also, is tach wire available at the instrument cluster?

[gotdubd]

all 4 doors are a common trigger wire
trunk is a separate wire

and yes tach is at the cluster. i dont remember off hand what color it is. blue/green maybe

Trunk Pin White/Black (-) Above Driver's Kick or Anti-Theft Module
Parking Lights Gray/Black L Green/Red R at Light Switch Isolate (tap both wires and diode isolate them)
Hood Pin Brown/Red (-) Alarm Module or at Pin
Door Trigger Brown/White (-) Driver's Kick Panel Blue Connector or Alarm Module
Door Lock Gray/White (-) Negative Pulse to Lock Double Pulse Unlock
Door Unlock Red/Brown (-) Hold Ground to Roll Up Windows Driver's Kick

i found the parking lights and tach wire, now ill need to find the trigger wires and lock/unlock.
thanks for help

still cant find the trigger wires.
what do you mean by blue connector at drivers kick panel, is that the blue connector that plugs into the instrument cluster? if yes than there is no brown/white wire.

how exactly do you use multimeter to find trigger wires, i just want to make sure i do it correctly.
MM is in DC mode. I attach the black wire from MM to ground and connect the red wire to the wire i want to test? when door closed the reading should be 0.0 when opened it should be something else, right?

also you said there is one cummon wire for all 4 doors, but at the instrument cluster it shows separately each door. it shows you which door is opened. doesnt this mean there should be a separate wire for each door?

[Gregor2004ua]

just want to make sure.. is this the alarm module??

12volts closed. 0volts opened.the blue plug theyre referring to is wires in the kick panel coming out of the drivers front door. i promise theyre there. that brown/white controls all 4 doors no matter which one is opened.

i understand youre willing to do this and learn but you may want to leave this to a professional, its real easy to fuck something up real quick if connected incorrectly

ill just give it one more shot tonight.

[whoace]

I installed a Compustar on my 01. All the trigger wires are located at the Driver Side Kick Panel. You need to remove the trim piece to the left of the dead pedal.

I don't recall what colours the wires were but I do know that none of the wiring diagrams I pulled (Alldata, Mitchell, 12volt) had 100% accurate colours. I ended up backprobing all the wires to find the triggers.

I got the tach sensing wire at the ECU. I found it a lot easier to splice into there.

That module under the back seat is not the alarm module. It is the module for the sound sensors.

what about lock/unlock wires. did you get them under drivers kick panel too?

yes

[Gregor2004ua]

yes

just finished a successful install tonight.. everything works fine....
thenk you all for the help..
ill post some pictures and the wire colors for all triggers and other stuff.
thank you guys again ...

[Frizo]

Put up some pictures when you get a chance if you dont mind.. I have a compustar sitting here waiting to be installed in my S4 and I'm sure wiring is very similar. Congrats on the install

nice dude! does the factory remote stuff work too? like windows up and windows down from the remote?

[Dallas09]

Glad you got it.


Yeah the window roll up isnt hard becuase you just wire an Auxillary to the same lock and unlock wires, you just hold the ground instead of pulse it.

[Gregor2004ua]

yeah.. the original remote works just fine.. but it doesnt unlock the aftermarket alarm.

[Gregor2004ua]

i just noticed that when the car is remote started everything works fine but the Climate Control. It doesnt go on. If i insert the key in ignition and turn it to ACC, it turns on. I guess there must be a separate wire in the ignition to feed the Climate Control.

[whoace]

You must have fed accessory power off the 75X terminal and not at the ignition switch at the steering column. Mine works fine. I'm in the process of wiring in a 30A Relay off the 2nd accessory of the compustar to get my rear defrost working with the remote start.

I fed it at the steering column. I connected the ignition power wire from compustar to the black ignition wire at the ignition. I thought that if i power up the ignition it would power on the ACC, i guess i need to connect power to one more wire.

[Dallas09]

I fed 75x in place of the black and yellow wire, becuase if you trace the wire from the ignition to the back of the instrument cluster the wire changes gauges... (theres two wires one from the ignition cylinder and one from somewhere else, the wire from somewhere else keeps its same size but the one i thought went from the cylinder to behind the cluster changed gauges so I didnt think it was the same wire if that makes sense its kinda hard to explain). Anyway i connected to the 75x in place of yellow/black and then did the rest of the wires normally, my climate control works fine.
