Iam finally getting around to installing that Warn M12000 I purchased from a fellow ih8mud member at the beginning of the summer. I did a search, and have talked to Warn today.but I still have two questions. The 'motor ground' Item #30 in the diagram - this attaches to the bolt on the oposite side of the warn winch that has the F1, F2, and A Terminals? I'am 99% sure, but wanted some input.

Papka po samoobrazovaniyu uchitelya informatiki. Warn M12000 with serial 46980 KM1 winch PDf service repair manual below. Proper use Motor is replaced with 24 Volt series 9: Warn mrv-c-3, M39333 D Bo.

Also I have a 6 ft black 2 guage cable with rings on both ends. Iam assuming this is a extra ground cable, but where do I use it? Maybe from the Truck frame or engin block to the warn winch? Maybe to the same bolt as #30? I've emailed Warn, but I want to finish this up tonight, and Iam sure they won't get back to me until the next day. I hope your experience with Warn was like mine, they sent me full wiring diagrams, called me back, and sent some gratis parts all to get an 8274 back on the road that I bought used. Great customer service.

To answer your question: you're on the right track. The small ground wire can ground anwhere on the motor, but they do provide a lug, and it is on the back side as I recall. The long black wire is to run from the same motor ground lug directly back to the negative terminal on your battery.

The winch does not ground through the frame-you will need to go direct to the battery. Edit-Poser beat me to the punch.
