89 5.7 TPI Alternator Wiring
Have an 89 IROC with TPI. Harness is pretty good with a couple of small issues. Alternator has 3 wire connector - Red - Tan - Brown. Brown wire has been cut and doesn't route anywhere - where should it go?

The heavier red wire goes from a Fusible Link, to the positive stud, and should have power at all times.
The thinner red wire goes from a different Fusible Link, to terminal S (the sensing circuit) and should have power at all times.
The brown wire goes to terminal F (the turn-on input) from the FAN fuse, and should have power when the key is in the RUN position.
