Recently purchased a 2001 case 90xt. The parking brake button is missing from the joystick and the 2nd speed button has no effect. I took the back cover off the joystick to reveal the switches and wiring. Someone in the past cut a wire, spliced some wires, and twisted two wires together. Can anybody provide me with a wiring diagram or tell me which wires do what?? They look to be original wires, so colors are hopefully correct to manufacturer. I want to replace the brake button and see if I can get 2nd speed working. I know my way around electrical switches, circuits etc. If I only had an electrical wiring diagram... Thanks,
