As this motor is out of a C6, figured this would be the best place to ask this. Here's, what is probably, a stupid question. I'm reworking a 2008 Corvette LS3 harness for install in a 1968 C3.
I have a red/white wire from pin D on the generator (alternator) plug going back toward the ECU. It does not have a place to go on the ECU. I'm guessing I need to route it to a 12 V+ batt hot supply.
Then it dawned on me, does this connection NEED voltage, or does it SUPPLY voltage.
I'm at a loss to where this wire goes.

Reason: Placed in wrong forum, should be in C6 tech/perf
That wire supplies voltage to the alternator to: 1) let the regulator know what the system voltage level is and: 2) to energize the rotor field coils as commanded by the regulator.
On the C6 it goes from the alternator to B+ by way of the horn/alt sense fuse and is hot at all times. So yes, on your C3 connect it thru a fuse to B+.
Be sure to post pictures of your resto mod project.
