Your pic doers not show just where wire 2 goes but appears to be to the FSS which would go to the keyed source.
For wire 1 you will need to check what it attaches to but if it is the KSB then also goes to the keyed source.
Wire 2 does not look like original wiring, may have been bypassed out of that harness.

Right, looks like there is another wire on the FSS, that usually goes to the temp sensor for the KSB.
Guess you need to be tracing some of that wiring.

Char,
Is that a resistor setup like on some of the later units? Should be able to reproduce that.
