Wiring Help Upgrading to 1 wire Alt

[73pony]

OK. I am not good at reading and understanding wire diagrams. The pic below is of the wiring instructions. I need help identifying which wire in the car is the power supply to fuse box from under the hood. Thanks in advance.

This thread has additional diagrams and discussions about alternators. The latest version of the diagram is in post #5
The diagrams also include a single wire diagram.

Alternator and Regulator Wiring

I've thought about making up color-coded wiring diagrams focused on the alternator and voltage regulator for some time. The question came up again the other day on how and what the different wires were connected to. So, I decided to do it, one diagram for cars without factory ammeters, one for...

The heavy Yellow wire in the engine bay harness feeds the fuse block. It will be attached to the front stud of the starter solenoid.

Yep, you won't want to run a wire all the way to the fuse block. You have 2 sources to use for your B+ the wire Hemi killer mentioned or the junction block that your original alternator harness went to. It's big black wire w/a orange stripe. Mine was on a 73. As far as the the rest, there's still the source voltage whether or not you have the gauges or not. One follows through the ammeter the other had a idiot light.

Perfect. Thank you. I was thinking it was the yellow wire.

That seems to be related to a Painless wiring harness, I have never seen a split/loop like that…
