I am afraid that I already know the answer to this but: What chassis electrical wires do I have to keep...The wireing in my 30yr old car is basically useless (unless starting fires counts) Can I go with a aftermarket generic wire kit ie: Painless or am looking at re-wireing the whole car. Mfg replacements are not available. Do I have to keep headlights,parking lights,horn,turn signals? In the book all I have found is "All chassis/structural/electrical repair if performed shall be in concurrence with factory procedures." By that my thinking is I have to manually re-run each wire.

thanks
