Have 80's Brute 750, 12/24, 41# thrust with the large foot control, I picked up a newer control also 12/24 to switch out with large control. When I got into checking things out, I found that the old control along with the head and motor have 6 wires (Red, black, blue, yellow, white and green), the newer control has 5 wires (Red, black, blue, yellow, white). I have no idea what the green wire is for. I can not find a wiring diagram. Has anyone run across this before or have any ideas on how to wire in the newer control?
