Ford Ranger Preplacement panel
This will replace your stock plate in your tub so you can add in a 50 Amp Anderson plug or 12v socket.
Replacement plate and Anderson style plug
Replacement plate and 2 x Anderson style plugs
Replacement plate and 1 x Anderson style plug and 1 x 12v Marine socket
For the 12v plug, you can use the factory wire but for the Anderson plug, I would run new wires from the battery with a fuse. For more information please contact your local auto electrician for help.
Beware: This polymer is very tough and has some flexibility but when it does fail, it cracks rather than deforms. Do the screws up firmly but do not overtighten.
