    Can anyone tell me or point me in the right direction on the external coil version of the GM HEI unit? I have searched the forums and only found the internal coil mentioned. In particular, I have an HEI with the coil external. I will be picking up my plug wires, cap coil and rotor tomorrow. I have already swapped the gear. I know taht I need to use a relay to supply the 12v to the system, I am just not sure where in the "external" version I supply the ground and 12V.

    Thanks and have a great day!!

    Mike :cheers:
