I bought two 15' of 2/0 welding cables off eBay.
I ran both + &. - from winch contactor on RH of the ARB bumper, to under the radiator, then left and up along to behind the horn and the wheel well cover, down the cover near the brake booster, along on top side of the frame rail, then to the battery.
I covered the + with those high temp corrugated plastic wire loom. Double wrap at certain rub-prone spots. Zip tie so cables don't move.
End to end, 13.5 feet used for each.
