Thread: Wiring Schematic

Tweet

Does anyone have a good wiring schematic for a SBC engine? I have a one wire alt., mini starter with two big lugs and one small, a three wire HEI.

I did get my horn to work though, sure is loud!!!

What really is it that you need? Did you buy a wiring harness? If so it should tell you what goes where. I can help but need to know what you are starting with...

I bought an EZ wire harness and I think I have most of it figured out except for the distributer. It's an MSD Streetfire HEI with a three wire plug coming out of it, red, yellow and black. Can't seem to figure this out.

Oops, I just noticed it has another place for a plug under the black cap.

The 3 wire plug is probably from the base of the distributor to the cap... The wiring to the distributor should be a 12V+ lead from the ignition "on" position, then another terminal for the tachometer connection.

Thanks Dave, I finally found a picture and realized the plug goes to the cap, that's what had me confused. So I got IGN Switch and Tach to the HEI and ALT power and the ALT Bypass to the starter with the bypass going to the Alternator.

Thanks again,

Sean

There ya go Sean, should be all down hill from here!!!! Hope the rest of the wiring goes well for you, sometimes it can be a real bear....
