Sorry I took so long to reply.

I had mine permanantly wired to the battery and ran the wires back into the back of the van to keep them out of the weather. I had a dual post battery at the time and used the top posts for the van and the side posts for the winch.

If I were doing it now I would look at hooking the pos cable to the battery stud on the starer. Should be a littled easier to hook up.
