HI.. I am in the process of deciding to replace wiring harness for a 70- b-Body.. has anyone replaced one recently!.. What is the best Harness on the market... and is it complete with fuse box.. ect...!
I saw on Classic industry mopar suppliers they sell:
Painless & Ron Francis

please help.. Thank you so much!

M&H is another option: http://www.wiringharness.com/

+1 for M&H never had an issue with their stuff and it's just like the factory, regarding colors.

M&H is my only consideration in a build, but regardless of the mfg you choose, take the time to compare it to the original, as well as the factory service manual diagrams, and take the time to check continuity of EACH circuit with a quality meter BEFORE you install it

M&H

Just put one from classic industries in my 70 Charger. I'm happy with it for the most part, everything works, only complaints are the door jamb switch wires do not fit through the holes in the pillars and the turn signal switch and ignition switch plugs are very tight and hard to get plugged into the new under-dash harness. Not sure what brand they sell but would buy another one IMO.

Put an M&H in my GTX dash. Everything was good with the exception of the 5 wire gang plug for the printed circuit board. I ended up cutting their ends off and finding correct bullet connectors at my local electric supply house and used an original plastic connector holder. So far so good.

M&H....From Year One.... with a 30% off deal...

Be prepared to wait a bit....

I put one in my 70 RR about 5 yrs. ago.Year one with the 30% off.M&H makes the best one IMHO does comes with fuse box.I also did engine bay and back lights.No cutting at all color coded,easy to do.
