What are you looking for? GMCpauls has an wiring harnesses modified for the upgrades you have made. The engine harness modified for HEI and the Headlight harness modded for the int. regulated alternator.

For the HEI wiring, you'll need the engine harness, and the forward lamp harness for the Alt conversion. I got my engine harness from "Mothertruckers". He custom orders them they way you want, and great prices. Worked great....That's not to take anything away from GMC Pauls......Their products are also good......

As far as my forward lamp harness, I did my mods to the alt. where the external reg. was and retaped everything. That way, I didn't have to buy the forward lamp harness. Looks factory.....
