Adding a headlight relay harness isn't bad at all. You can buy one from several vendors are make one for cheap. I made all 4 of mine going about 10 years now. Hasn't failed yet in the 71 C-10.

The newer alternator with a internal regulator is a good way to go and it's a easy swap with the 94amp one its a direct bolt in. Uses the factory brackets and the wiring is easy. There are several write ups in the electrical section.

I found this for the battery harnesses.
