Rayline/Jabsco 5" 61025 series spotlight control wiring

[Jfreder228]

I am finishing a complete dash replacement/rewire on my 1989 Regal Commodore 320 and am stumped by the connection of the motor speed control pot to position control switch. The position and speed control did not work for the previous owner and someone prior made some attempt to rewire and bailed on it to use the power wires for other accessories.
I have the wiring diagram showing interconnections between the control panel and light but I have no reference for how the speed control 2 wires connects to the position control switch.
Does anyone have a wiring diagram or picture?
