Can anyone point me to a link that would have a complete wiring diagram for a 1974 Challenger? I just got the car off a neighbor, originally a 318/3 speed - He put in a 440/4 speed, and for some reason removed the entire wire harness. Car came with 2 Harness's, and a new engine compartment Harness. any help appreciated.
Thanks, TJ

If they don't match then Mitchell or Motor had the wrong diagrams.........

Replaced the dash harness in my 74 with one for a 73 from year one. Just to get rid of the seat belt starter interlock mess. There's other ways to bypass it, but mine had melted down at the bulkhead connector due to a short in the alternator, so had to buy a harness anyway.
