2001 Chevrolet Cavalier

I need to find the wire codes for diagram for installing a keyless entry system to a 2001 Cavalier.  I mainly need to find the horn, parking light, and which wire on the door pin switch to hook up.  I cannot program it to lock when the key is turned on, but I can get it to unlock when the switch is turned off.  Could I have the door pin switch wire hooked up the the wrong one.  I am installing an Audiovox APS-45b.  Thanks for all your help.Terry

Chevrolet is very wierd when it comes to thier colouring, now with the Audiovox piece isn't that strictly in programming for ignition lock and unlock, check the manual for that one.  Horn should be a smaller black wire in main column harness or bigger harness going into the firewall runnig with the mains, should be a negative pulse.  Parklights should be brown, but other colours I found them to be are blue or white, depending where you get the source.  Kickpanels on those cars are usually the best place to get everything.  Doorpins, are you meaning doorlocks?  Let me know what you mean.  You shouldn't need doorpins if your just hooking up keyless entry, right?  Unless your having it be an alarm/keyless entry.Kyle@Audio Obsession Sound

the black OEM Horn wire is also located in the steering column harness.
