Big live feed in there, I think it is connected directly to the battery so would work fine. Don't neccesarily need a specific harness, to wire into the back cubby, just need to find a +ve and ground. Could wire in a decent waterproof connector and feed it through the grommet for the trailer wiring. There is nothing that can't be fixed with a hammer😜😜
