My finace has a POS Dodge Avenger and she wants to add keyless entry. There are several places on the net taht sell a CRIMESTOPPER unit for $30 that will unlock the doors, pop the trunk and toot the horn when you are and disarm which is what she wants.

Now, I am a bit worried about the instal. Is this going to be tough to do? How will I know which wires to tap into for the horn? The ones for the power locks wouldn't be to bad as I can pop the door panel off and look. Any advise outside of buying a shop manual?

Thanks,
SHUMAX
