Good day to all you guys and gals. I am swapping a 5.7 out of a 1990 model. It's been a while sence I have done one of these and the wiring is killing me. I need a good sourse of info for the wiring sceme of this unit. The owner took the wiring lose and now we have a mess. One issue is when I crank over the new motor, the nutral safety switch wire burns, along with other wires not hooked up. HELP PLEASE. Thank you in advance. my E-mail [email protected]
