I have a NOS under dash wiring harness for 57 Fords with a V8. The part # is B7A-14401-A. The tag on the harness is FEH-14444-5.
Everything is there and in perfect condition. There is even a fuse in the in-line fuse holder! Asking $375 or make me an offer. Text me at 907-575-5099 if you are interested. I have this listed on ebay as well.
