Apex Nano Side Marker Plug

This is a filler plug for the side marker lights on a Coachmen Apex Nano trailer. The factory drills a 1.5" hole to run a couple wires through. This plug fills most of the hole to make it easier to seal with silicone. I sized it just over 1.5" so it should fit snugly.

Feed the wire into the slot. Push the plug just below the wall surface. Add some silicone in the slot and all over the face of the plug. Smush the light into the silicone and screw it in place.
