fd alt wiring diagram
 
Thank you for posting what was in the FAQ. My question isn't what each individual plug does. I'm looking for a diagram to show where they connect to the harness. (The T plug and post) I have the post connected but the T plug is where my confusion is

The T plug has a W/B wire and a B/W wire. The W/B runs to the largest plug in the CPU. If you look at this CPU plug you will notice the W/B wire and it's the same wire at the alternator. The B/W wire runs to the 15 amp engine fuse of the interior fuse box but this is for the S4 alternator set up. On the S6 (FD alternator) the B/W wire needs to have constant voltage and thus it runs to the engine fuse box and ties into one of the fuses there or you can add another fuse in a vacated spot and run the B/W wire to it.
