A truck camper is a recreational vehicle that you can attach to a pickup truck. You may also hear it called a slide-in or cab-over. A truck camper can go anywhere and withstand the rough roads, so it brings the amenities to off-road camping. If you are considering towing a truck camper behind your pickup, you must do some rewiring ahead of time to make your camping and traveling more comfortable.

You will need electricity to access your radio, use your electronic gadgets and operate your taillights. Your truck camper operates like your regular home, so expect that you will have electricity even while you’re traveling rough roads.

Step 1 - Remove Fixtures and Exterior Sheets from Your Truck Camper

Once you have decided the new location where the wires should go through, check that place for any obstacles such as water supply lines. Next remove all the lighting equipment, outside connectors, outlets, and so forth inside the truck camper. Take away the angle and joint casts that can be found along the windows. Then organize and store your hardware materials and equipment in a convenient place.

Remove the external sheets. Use a screwdriver to remove the screws that secure the sheets. Removing the sheets will give you extra access to where the wires should go through. Use the battery drill with bits to make a hole for the new outlet location.

Step 2 - Trace the Wire Harness

Before installing wiring, you may need to trace the wire connections with a pencil and paper. Make a realistic sketch of the wires. Label where each wire goes to and comes from. Also note the wire colors.

Step 3 - Run the New Wiring

With the drawing as a guide, you may now install the new wiring or add additional connections or outlets. Run the red and black wires, starting from the newly set outlet towards the battery or converter.

Fold the wire ends and attach them to their corresponding partners. Red wires should go to the inline fuse holder and black to the battery wire. At the newly set outlet, connect the red terminal wire to the positive post and the black to the negative one.

Step 4 - Finish the Installation

Replace the stuff you previously removed–the exterior sheets, the trims, and moldings, fixtures, connectors, and outlets.
