Question about wiring and about switches
First off, Im looking to replace the switches that came with my Rigid Industries wire harness (seeing as the backlights failed in under a day). I was looking at the style of switches shown below but I would also need to find a three position switch for my heated seats. Any recommendations? I need something that I can find in an On-Off configuration as well as On-Off-On with backlights for the On.
Bonus points if they are relatively shallow mounting switches as I dont have all that much room where I want them. And a .5" hole size for mounting would be rather convenient too.
Secondly, can I tap into the circuit that turns the lights on when I unlock my Jeep and have that also turn on my light bar backlight? Also, is there a good way to tie in to the headlight switch to have another light power on any time the headlights are on?
And as a bit of an after thought, my left 2 switches on the factory panel are blank. Has anyone ever replaced these with switches instead of blanks and used them to control lighting? That seems like a pretty clean way to install them.

Here is a description of what the headlight switch does:
Headlamps - The headlamps are requested when the left multi-function switch control knob is rotated to the headlamps ON detent position. The Steering Control Module reads the resistor multiplexed input from the left multi-function switch and sends an electronic exterior lighting switch status message over the LIN data bus to the EMIC, which relays an electronic exterior lighting switch request message over the CAN data bus to other electronic modules in the vehicle.

The days of having "tap-able" power for the headlights pass through the switch are over.

Tying into the headlights isnt all that important but I was thinking it would be cool to do while Im rewiring some things.

There is no usable power there. It's a resistance circuit. The computer reads resistance according to the position of the switch. Adding a relay's coil to that circuit will change the resistance the computer sees.

I was more so thinking about the wires going the lights themselves.

Why not tap the wire to the marker lights. That is what I've done. Marker lights are on when the headlights come one, so anything I have tapped to that wire come on with the headlights. It sounds like that is what you're wanting. My jeep is wired for towing behind a motorhome, so I've tapped the various wires running to the back down in the front passenger footwell area. Pretty easy access.
I have lighting in my footwell area and speakers that are triggered off that wiring. Headlights on, nice soft glow in those areas.

Anyone got some suggestions on the switches? Ive seen a few varieties but they dont seem to have many specs regarding mounting depth. I might just order a few various samples but I'd rather save the money.
