Obviously, winches draw a lot of amps and the more amps you can supply them, the better they will work. The standard battery leads that come with a winch won't be long enough and will not be thick enough to ensure you don't suffer from voltage drop. For one Domin8r X rear winch install, the cable length was over 5m from the start battery so heavy gauge 2/0 AWG cable was used to power it and overcome voltage drop. When running this cabling from the rear winch back to the battery, the trick is to hide it along the inside of your chassis rail (not within), insulate it and cable tie every 300mm and don't forget a good inline fuse or circuit breaker close to the battery (more on that later...). That will protect your wiring and your other electrical components from any harm off-road.All Rights Reserved
