Y'all are going to get tired of me with the wiring questions, LOL. I'm not against paying someone that can share the know-how I need to get this done.
I have looked at the foldout WD for hours, and I can't find an answer to this. The question I have right now is, the black/yellow starter signal wire coming from the Interlock Relay, goes to a connector that also has a thick gauge white wire. See the two images...

In the 1991 FSM, it shows this plug possibly as E19 with the black/yellow starter wire coming from the Interlock Relay going into the E19 to E204 connector but I can't see what the white wire goes to. There's nothing about the white wire.

Where does the white wire lead to?
