Tested winch, rock solid. Getting the front to rear charging kit as the flat four, won’t give it enough angry pixies. Bus bar for battery already in place.
The following connector goes from the front of the trailer to battery tray.

From what I can tell this was a cannibalized 1500 amp jumper cable set. They run about 60 on ebay. Theory is undo the nuts on the clamps and attach to truck battery up front. Would run it along the left frame rail and route to the hitch from there leave some extra feet to cross over, when done i would fold the cable and store in the underside. The wireless remote is nice!
