wiring harness...
 

i have a 1979 dodge adventurer and basically the old lean burn was taken out of it and the original owner put in an older carb, but left a lot of wiring just laying around, its just a pure mess, i was wondering if anyone knew if a older wiring harness would hook right up to my firewall without any further tinkering around, or wold more have to be done for it to work?:confused:
