66 Valiant Electrical Issue?

Thank you sir.

I'm going to go ahead and rewire the engine harness for the later style regulator with a single ballast resister. The ECU plug is a 4 prong.

Have any recommendations for a good quality ECU and volt/reg I can get from a parts store?

Also, what about headlight relays? I might as well modify the lighting system while I'm at it. Wonder if any parts stores carry any relays that I can wire in?
