I've taken a higher resolution picture of what the FSM figure was trying to show. Gotta love those grainy FSM closeups.
I'm trying to track the wire off the sensor which was depicted in attachment 1 of my thread starter. I appreciate the photo and had indeed saved a picture of that unit. To point out my error, the wiring appears to travel back through the firewall so I'll add it to my list of which wire to rob off this body and install on the SE.
