im looking for a wire harness for a 75 half ton with a 390. not sure where to look.

 

Never bought a harness myself, but Google came up with this, might want to call these guys:

Don't know how much electrical experience ya have, but the '73-'79 haynes manual and a couple spools of wire will get ya fixed up.

well its for my dads truck and he didnt want to mess with it. he just wanted to buy one and be done with it.

 

I just had to replace the wire harness from the starter solinoid to the altenator on a 90 F-150 4.9L. Went to the factory and "no one in the country" had it. Had to go to a junk yard to pull one. Dont know if your willing to go that far but its a thought.
