I ran all new wiring thru bulkhead connector. I did a lot of wiring upgrades. Everything I did I noted on my copy of wiring diagram. 100 Amp alt. Included. Two field. Amp gage bypassed. Lots of improvement s
And bet never going to be a electrical problem.
Used American auto wire kit on mine. Soldered all the ends on and used dielectric grease on the connections. Also got most of the wiring out of the engine bay. Hope it lasts a long time.
