I think I will do the Harness..someone was under my dash at one time...seems some of the wires start with the correct color and Guage and then...you know..the color changes and so do some of the Guage...it still starts and runs great,but I want it to be correct,so i can work on it.I really took an long look at all the wiring..they are extremly brittle,most of them coming out of the fire wall were covered in grease, and the wiring hooked to the fram under,are wraped in electrical tape...who knows what shape they are in,I still Have the genorator..should I switch it over..
