A T-tap was slipped over the wires to effectively allow power to flow to our tonneau cover's electrical system. You can see the tap on the pink wire here, with our red lead running from it. A self-tapping screw in a screw gun zipped right through the floor for a sturdy ground. A body grommet was near our power source, so we dropped the wiring through it, then buttoned up the carpet and trim panel as if nothing had happened.
