2006 audi a4 quattro

I am going to be possibly installing a Python 4203P w/ DEI 556U bypass in the car. Anyone ever work on one of these cars before? Any tips or special things to do?

Also, I noticed that the Python 4203P has door lock wires. This is just a 1 button remote starter. I never installed this model system, but im assuming I can just leave out hooking up the door lock wires. Can I do that? Im guessing the door locks on these cars are a pain.

I looked up the wiring for this car. It says to use a 250 ohm resistor for alarm disarm, same wire as arm. And it says straight (-) for alarm arm, same wire as disarm. I would only like to hook up the disarm wire. (I can already tell I might not like working on this car) So would I just wire in a 250 ohm resistor inline of the disarm wire coming from the Python unit? Simple as that?

Thanks.

Anyone?

Should I stay away from this car? I was thinking about just searching for all the wires and if I dont find them....just to give the car back to the guy and tell him to find someone else.

Ok...my first post is wrong. Looked at a wiring diagram for an Audi A6. My mistake. The Audi A4 doesnt say anything about using resistors for disarm wire. It looks to be pretty easy according to the Audiovox wiring diagram, but I bet most of the wires are wrong.

Anyways, the problem is that the customer bought the 556 and has a spare valet key for it. Do you really think I could do this alot easier if I used the CANMAX 400? I never worked on a Cadillac before and used the CANMAX 400 and installed an alarm/remote starter without problems. I know you cant judge my install ablities......

Ok thanks for all the info.
