I was given a Columbia Par Car Eagle, I believe it is a 1992. I got a Curtis controller and a three solenoid set up, Main, Forward and Reverse, but I have not been able to locate a wiring diagram for this setup with 7 wires coming from the Pot Box.
There's a few Columbia ParCar Wiring diagrams in the Resource section of the forum but I don't think I have one with a 7 wire pot box. I'll look tomorrow in the shop and see what I have out there. Welcome to the forum.
