Mallory 685 CDI Ignition box
Ive got this ignition box and im wanting to use it on a GM 355 with an HEI system. Problem is, this box needs a an extra harness sold seperately, but they dont make it anymore as far as the book goes.
Anyone have this box and have some know how on running it to an HEI dizzy?
