Switching to HEI...wiring question
350 in a 68 Chevy SWB. Have a points distributor in there now...going to switch to HEI soon. Question is...do I have to run a hot wire straight from the fuse box to the new HEI coil? or can I make a new connection out of existing wire that plugs on to the - side of the old external coil from the wiring harness? Now this wiring harness that is on there now is only about 2 months old, bought it from Rick's. Also what gauge should the wire be?
Thanks again! |

The wire in your harness is not a full 12 volts. The new HEI needs 12 volts. Just run a wire from the ING UNFUSED location and plug it into the new distributor.

Put a 5 amp inline fuse in that new wire also.

Yup, I second that. You cannot use the stock wire, as it is a resistance wire. You must run a new 12 guage wire directly to your fuse box.
