I decided to add marker light functionality to my mid-ship turn signals. This involved running an extra wire to them. The drivers side was pretty easy. The curb side involved some creative wiring to get the wire across. I wound up taking advantage of the stairs and carpet tack strips. I also used some DAP Silicone (adhesive) to hold the wire still and act as a grommet where it passes through sheet metal. This will immobilize the wire and can be easily be removed in the future if I need to.
Here is where the wire enters the coach. I’m coming through the wheel well. It’s sealed with silicone. Notice the wire label marking what the wire is. I like to do this at every penetration. It saves aggravation later.
The silicone is also good for keeping the wire in the crack.
A screwdriver can be used to gently coax the wire into the crack.
Spreading the silicone can be messy, but using a plastic fork/spoon/knife works well. Use the blunt tip not the eating tip.
I ran a bead of silicone up the corner of the stairs.
And here you can see me using the fork to push the wire into the silicone and smooth it out. I’m using a piece of cardboard and a tool to hold it down at the bottom.
Here the wire has crossed the coach and is coming through the back of the electrical space. It’s grommeted with silicone to prevent damage. I squeeze the silicone into the hole as well.Here the wire enters the electrical space. It’s sealed with Silicone to protect it from movement and subsequent damage.
