How to get thru firewall in front of driver

Recommended Posts

Need to put a wire thru the firewall. I only see one grommet and it looks like it goes to washer motor

What size wire? There is a small nipple on the main grommet on driver's side.

I'm with 1slow, there is a main harness down further from where the washer hose is. It's like 2 inches maybe or larger. There is a tiny nipple on the top of the grommet. I used a old metal coat hanger to feed in 3 12gauge wires for my remote start when I hooked up an aftermarket one. I plan to shove a single run of 0 gauge in there too next year for my system and if I can't I will make a hole just next to it and have it's own grommet for it.

If you lift up the driver door sill trim and look under the carpet there is a rubber grommet.  This is where the company that installed my topper ran wires for power.  I used the same access to run wires from my left-side fuse panel to a camera on my front bumper.  All wires are protected. out of sight and no drilling or coat hangers required!
