Two options I wanted in my truck but did not because of limited availability was upfitter switches, and trailer TPS. Does anyone know if the harness and/or relays for this is already in the trucks? Could the switches be purchased and installed as a 'plug n play' solution?

Yes. Easy install. About $270 to buy all of the parts. Few threads on here that will give you part #'s and some instructions.

I don’t see why we can’t pull the switch panel out and make them “spacer” become switches they look to be like they can be functionable and few years ago I seen where a guy had pull that apart cut plastic piece off and they are actually switches but this was older truck like 15 ish but I haven’t seen anything about 19-20 models where this is the same bc I too bought the grille insert lights and I plan to wire it up to the extra switches/spacers whatever you call them bc I believe they are in fact switches just not it use so they are blocked off, and same time I plan to install the auto stop eliminator just trying to research it more b4 I go into it as I’m waiting for both these items to get delivered so somebody tries this lmk!!!!

Were you able to tap into the auxiliary button? I have the same issue.

I recommend looking into this. It's not exactly what you're looking for, but it's an option. Scroll down to Technical bulletin 153b. https://www.gmupfitter.com/pages/technical-bulletins

Following - I'll need the Aux switches once I get my FabFours bumper on for all the extras

Also following... I'd rather use a blank switch than install the upfitters just yet.

I recently did the Aux switches, if I had it to do over again I'd either have gone another way, or possibly modified the Aux switch install. Mostly because to me having the relays/power wires under the dash is really inconvenient, most stuff people want to hook up are in the front end. So having run to run the small 12-14ga power wires back toward the hood/battery is just silly, plus now you have to find a way to run heavy power wire through the firewall because while the fused switches might be 20-30amp, the minimum wire gauge for a 10' run at 30amps is 10ga. Good luck pushing 5 10ga wires through that little firewall port.

I think if I was doing it again, I'd mount the fuse/relays under the hood and try to extend the wiring from the aux switches to the fuse/relay box under the hood.

That or just do it right the first time and use one of the new wireless aux switch setups.

The Ford Raptor has aux switches where our rear window/sunroof switches are, but the blunt cut wires are under the hood. Essentially, GM would have to include auxiliary switches as a package or else for all trucks.

I did this for my train horn install (2500)

I had the switch bank completely out. Mine come out in sections of 3. It looks like the board extends into the fake switch area and there is a button on there. I didn’t dig any further because my plan was to drill them for my switches.
I installed my switches here instead...

You have any photos of where you put the horn, tank, and compressor?

ScottNic · October 14, 2021

I have a 2020 Chevy 2500HD and I want to add a train horn and have it go to my aux switch. I cannot find anything on how to utilize the end blank/switch. My installer cannot find anything through his dealer network...

Can anyone lead me in the right direction? [email protected]
