Auxiliary light switches/firewall pass through?

I'm installing a few LED pods on the front of my van and am sorting through where to pass the wiring through the firewall and where to mount 2 switches.

I had originally planned to use round switches and just drill a few holes in the kick panel beneath the steering wheel......but once I started poking around I realized that panel has a fairly thick steel backing that seems like it would be difficult to drill through.

Anyone have photos of what they did? Recommendations?

Did you find a solution? I’m working on the same thing right now. There is one 1/2 grommet above the accelerator assembly that was empty on my ‘98 but I filled it already.

I wound up passing the wiring harness through the rubber that surrounds the steering column. It was fairly easy to find a spot that was safe and kept everything out of sight/fairly clean.

For the switches I wound up cutting a rectangle out of the steel kick panel, reassembled everything and then drilled the round holes for the switches in the plastic panel. It wound up looking really good.

I usually drill a hole around the throttle cable pass through and use a wire gland for the grommet and seal as a single piece. This setup usually works very well.

we routed the wires behind the drivers front fender, through the existing grommet near the drivers door (behind the fender) and into the drivers footwell. this kept the wires out of the way in a 6.0 engine bay and required no drilling. rebar wire is really helpful for this.
reference this thread for pics of how we routed silicone tubing behind the passenger front fender (same process for the drivers fender) = https://www.sportsmobileforum.com/fo...und-24032.html

here's how we installed switches in the plastic trim piece.
the 4-switch panel is soon to be a 6-switch panel.
It all avoids the metal framework behind the plastic.
