By aftermarket coils , I meant later model years , on one blog I read that only the green red or orange ones would work in that motor , the black ones look identical and are really cheap.
all 3 of the ones I have are op,en between the coil and the. Plug

ive found several badly corroded wires and replaces them I chose 14 ga wire not knowing the current or voltage drop

thanks for all the great advice
