Trying to find a link for adding Coil-Near-Plug to a 4 cylinder engine. I can't seem to find one. I have a air cooled VW engine with Holley Terminator 550-410. I want the ECU to handle my timing. I'm currently running MSD distributor, 6 BTM box, and 8253 HVC II coil. I know I need 4 coils, and a crank trigger, but I'm not sure 60-2, 36-1 or what? Holley 558-307 would be the coil harness I believe. Any help or links are appreciated.
