I started with a 20' long pair of jumper cables (2 gauge stranded wire if I recall). Cut off a bout 3 feet and wired to the battery and down to the front mount where I attached a quick disconnect. Warn makes them but they are expensive, you can save a lot of money with a generic pair (MileMaker?). I have both and quality is the same. Then I attached the matching quick disconnect to the wires that came with the winch.

I have always intended on routing the rest of the wire along the frame rail and attaching a quick disconnect at either end for the rear but haven't got that far yet. I must have been planning on the write-up once that was complete, but this will havae to suffice for now.
