Regarding the source of the alternator, I recommend getting the store brand rebuilt alternator from O'Reilly that comes with a lifetime warranty. The one I got from them has Remy USA embossed in the case, so it gives me a little confidence. I got a CS144 and put a v-belt pully on it. I probably over-bought on the alternator since I don't need the big one, but I was enthusiastic at the time. I would probably use the CS130 if doing it again, but considering the CS130's reputation for bearing going out I would definitely want a lifetime warranty one.

The stock wiring has a 10DN connector at the alternator. The adapter with resistor you show is what I have, I recommend it. I have the wiring like VetteVet shows in the diagram above, except I do have connectors and adapters creating that wiring. I plan to neaten that up by completely removing the wiring to the regulator area and spicing the alternator plug directly into the wiring with soldered connections and heat shrink tubing. I think it will be better than using male to female plug adapters like I have it now.

I would imagine it is enough to run electric fans. Just curious, why do you have electric fans? The most efficient setup is with thermal clutch, mechanical fan, and shroud.
