I recently put a Protosound one unit into an old Williams locomotive and i wanted to put an Proto coupler on it. The problem is I dont know which wires from the terminal to hook up. Does anyone have a wiring diagram?

Here's a wiring diagram that was posted here sometime ago. The Blue 4-pin connector at the end of the board is the coupler connection.

Thanks much.
Just remember the PS-1 coupler is not the same as the PS-2 or PS-3 couplers. Also, a TMCC coupler would work as well for PS-1.
Thank you kindly and I have a small bucket of PS couplers.
