Boat Buzz

I have a 1970 Roamer '58 aluminum hull that was originally equipped with an Autopilot. It's no longer hooked up, but the motor and chain are still there.

My boat came to me very light on the documentation side, and I'm trying to get the autopilot functional again, so I'm wondering if anyone has detailed schematics, specs, wiring diagrams, etc. for the autopilot system of this vintage that Chris Craft was installing.

Thanks!
