Hi, click here for the service manual for the M8000 winch. Wiring diagrams are included in the manual.
I was very excited to see the entire winch manual until I scrolled down to the solenoid wiring diagram. It is not for my winch. My winch (serial no. 270263) has only a 3 wire remote switch but has four solenoids, but they are like the older Ford car and truck starter solenoids, not like the "base" mounted solenoids as shown in this manual. They bolt on from the "back" and have a large terminal on each side (for full current) and two small terminals on the "front" of each for the control wiring. Can you please check this out and re-reply to me?
I found that one online. Any good?
