The hardest thing is the turn signals.... Everything else straight forward....I replaced all three harness on 66 Dart. Under dash under hood and rear. Built from scratch all three. KEEP ALL plastic connectors!!! Re use them. Makes it easy.. Of course a new bulk head connector.... On...
I do not think there should be full voltage on both points on coil. One side is for "ground" Not actually with electronic but same function. But I might be wrong. @Mattax will for sure know for sure!!!
Had a convertible 69 340 Dart. Kind of quick. took it to Track in Fontana, A NHRA track for a test and tune event. No way a run with out a roll bar, told me it was to fast. How do you know? It sounds and looks to fast....End of story...
