Default keyless entry install

Hey, I have a 1996 A4 2.8 Q and it was not originally purchased with the keyless entry option, so I am installing an aftermarket system and just need a little help finding the location and color of the lock and unlock wires. I installed a similar system on my 1988 90 Q, and that system only used one wire for lock and unlock so I had to set up a couple of relays to make it work. It seems like the newer central locking systems do use seperate wires for lock and unlock, and unlock requires two impulses or something, I just need some help finding where they are located. Any help is greatly appreciated. Thanks.

Thanks for the tip, I'll check that out, but my car never had the factory keyless entry, so do you think the wiring would still be there? I'll look at that.

Default You car probably does have keyless entry

I did a ton of searching old posts and got it to work in my car. I got lucky and was able to turn mine on with just a used remote off ebay, but what I found during my search is that almost all of the cars have keyless installed. It was designed as a "dealer option" meaning that the dealer could turn the system on for additional cost to the buyer. From what I understand, if you can get someone with a vag, they can turn the system on for you. You'd then just need the keys and remote and follow the instructions for recoding the remote in the tech section. I saved the text off the old posts as a Word document, so email me if you want them.
