    The ping control will hook up to an HEI distributor however there is a harness needed to install it which is no longer available. If you would like to a schematic please provide us with fax number or mailing address and we’ll gladly send one to you.

    fax# 909-447-4433. Note-I (H-O Racing Specialties) used to be an MSD WD from '75 to '96. I might have the harness in the "old misc. MSD parts drawer". I still have an old"Dynamic Dynomometer",one of your earliest products.

    I'll have that diagram on its way. Hopefully you'll have the harness you need. Could it get better than that?
