Welcome to FABO best thing to do is get a hold of some long test leads,a good multi meter, a continuity test light and unplug the ignition switch... start with your most common problem I.e "no start " and refer your wiring diagram ... break down the circuit . One Issue at a time and you'll find it's easier then it looks... voltage drop test grounds. To body and motor most over looked problem in restorations and engine swaps or engine face lifts. Good luck
