I recently purchased a 76 FJ40 that had been sitting in a field for 20 yrs. Rats had chewed up the wiring inside and outside of it, even the copper. I bought a used harness off a 76 FJ from a cruiser parts place and the wiring harness has a 3 wire plug on the alt wire. Mine has the original aisin alt with external regulator, ignitor and rheostat mounted on the fender. Mine has a 2 prong plug. I have 3 different wiring diagrams and the colors dont match on any of the 3 to the factory harness. I dont want to fry anything so i havent been able to hook up the alt and regulator. I have lots of pics of the alt and wiring but need help resolving this issue. Thanks for any help..... not my first wiring job but my first toyota... Its a little intimidating....Points distibutor BTW.
