in the legacy body style, it's been a mixed bag, some people had a wiring harness that already pinned out all the switches, but didn't have any relays or battery/switched leads. some people had nothin

Looking for an auxiliary switch that'll mount directly in the factory locations and haven't been able to locate any GM part options.  I'm trying to maintain that factory look.   Is anyone aw

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.

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?

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]

      Is it time to put a piece of tape over the CEL?

      2015 Silverado 3500 right rear turn indicator failure

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL

      Tire pressure for 37s

      By Chuck FB · Posted

      First off you mentioned "Toyo Says" and then gave the pressures 45/50, was this some person at the tire shop that pulled those numbers out of his head ?   Now of course I can't know your exact axle weights front and rear, however I have much the same pickup as yourself other than not knowing your starting weight as per the pounds the truck rolled out of the factory at due to the options yours did or didn't come with or what you have added beyond the extra tire weight. The correct way to know 100% where a person is at is by weighing each axle with the typical weight the vehicle is driven with and that means taking into account passengers and making sure you figure in a full tank of fuel and a little grace for whatever you may put in the bed "groceries" !    I am looking at and not that it really matters as all the tire companies use the same charts anyway, but I am looking at the comprehensive Toyo tire chart in the section that your tire falls under and I know it sounds confusing but your tire is not an LT metric tire like your factory tire but instead because its a standard inch measured tire its under a different category called an LT floatation series tire. That makes a difference as LT metric tires they don't want to see run below 35 psi at highway speed where as with the LT floatation series it can be run down to 25 psi on the highway as long as the weight on the said size of tire is agreeable with or less than that minimum 25 psi. It blows many people away that how is this physically possible, an empty truck for one thing and larger tires with the same size wheel diameter have a lot more air volume so they can carry the same weight as the smaller tire with less air pressure.    So my truck, I have the stock 275/65R20 wheels and tires and I have a bit of weight in the box with a bak flip cover and a rubber bed mat and some tools and spare gas. The front of my gas truck weighs a bit more than some trucks of the similar spec due to double batteries and alternators. However with full fuel and just me in the truck I am weighted such that I can run 40 front and 35 rear and so that is what I have done since day one.    If I base your truck at or slightly below the weight of my truck, in theory with your tires going by the tire chart you might be right around a minimum of 30 pounds front and 25 pounds rear. Of course that would hit pretty much minimum cold inflation pressure one could run with that tire size and a near empty truck. If you have access to an accurate weigh scale to do individual front and rear axle weights I would suggest you do that and make sure your topped up with fuel and whatever else in the truck before you weigh it and then you will have a great starting point to work off of and figure out what your bare minimum pressures are you can safely run. If you do much in the way of hot weather high speed driving, bumping up a bit for a safety margin is never a bad idea but just depends on what type of driving you do. I will include the Toyo chart and the floatation series sizes start on page 31. Without a doubt at these pressures I am speculating at minimum wise for your truck, it would most certainly ride very different then it did when you were using 55 lb front and rear.     https://www.toyotires.com/media/pxcjubjs/application_of_load_inflation_tables_20200723.pdf
