Craig, I also have the Gary Russell 2-prong brake switch on my T/L system, but some reason I've lost the wiring diagram as how I converted it from the 3-prong switch. Do you by chance have the wiring diagram?
There was no wiring diagram per se provided with the 3-prong to 2-prong kit from Russell, but between what was provided and my testing of the operation of the relay at the time:
On the relay:
30: 12V pos always on (this is what had become disconnected on mine)
87a: normally closed (torsion level normally on; Lt Green wires from underdash switch output side)
85: brake switch power (Dk Green wire)
87: to brake lights (Dk Green/Black; comes on when 2-prong has pressure)
The stock underdash on/off switch has Lt Green wires and is unchanged.
The 2-prong switch has the Lt Green wires that are normally there.
