I need to know which terminal on the firewall connector sends 12v. to the fuse block. I got rid of my factory harness in the process of ditching the TPI. On the stock setup it comes from the starter through a fusbible link through the harness and to the fuse panel.

Try pin "A4" of connector C100 on the driver side firewall.

FWIW, I found my shcematics and pin A4 feeds the ignition switch and switched circuits and G5 feeds constant circuits.

Yes I know, there are many wires that branch off and feed a multitude of systems from "A4" that include the ignition switch and the fuse block.
