My 64 wagon was converted to an alternator by some unknown miscreant and the wiring is kinda cobbled up.

In short, I replaced the Delco two wire unit with a one wire model and I have some wires to decipher.

The big black wire that runs over to the starter connects to the remaining terminal on the alternator, right.

The Idiot light wire (small red one) goes to terminal 2 of the alternator?

The remaining small black wire goes where?

The harness these wires are in, looks original.

The regulator is long since MIA.

Thanks
