Less wiring from alternator please...

Hi, I'm in the process of wiring my car and have decided to use a small GM alternator out of a 90's Cavalier, besides the main post to the starter there is a plug containing 3 wires, brown going to the idiot light(charge indicator), a brown w/white stripe going to the heater/AC fuse and red 10 gauge wire that joins the red wirie from the main post after it goes thru a fusible link. My question is...can I ditch the brown/white wire altogether, put a resistor on the brown wire which ran to idiot light and can I run the red wire right to the main post. I don't want all the wiring showing. Anyone?

You can leave off the idiot light wire if you don't want a light. The brown/white wire is the regulator sensing wire and is needed. Yes you can run the red wire to the main post without a fusible link.

My schematic shows that the brown/white wire goes to the heater/AC fuse of the fuse block which is HOT IN RUN, I'm not running heater or AC, where can I connect it then??

Oh, do I connect it to the ignition switch at the 'run' post?

The best place is to whatever accessory that is drawing the most from the system. If you aren't running any accessories the ignition post would probably work.
