Help with an OLD trolling motor need wiring diagram for foot control pwr head

[gone fishn]

This is a Silvertrol and you can see the head says pathfinder on it. the foot control buttons and switches are all corroded and shot. I opened the motor head up and it had got wet and was all rusted up, But I have cleaned it sprayed it with cleaner and have gotten the motor to turn and I can get it to spin under power 12vdc with a jumper on the red and green wires. I don't want to spend 400 bucks on a new one if this is salvageable, with some new switches and dials I think it is. the boat is a old duracraft and my tiller is a '62 evinrude 10hp so flashy stuff has no bearing. so If anyone can help with wiring diagram or anything it would be greatly appreciated.

Don’t need a schematic to replace potentiometers (dials) and switches.

Remove, identify and replace. Should be common off the shelf parts.
