Very cool! Check out Waytek for the wire. They have a great selection of automotive crosslink wire.

@TinkeringFox thank you very much for all your efforts at figuring this out for everyone...

 

Thanks everyone who took time to make this thread as awesome as it is!

So if everybody is wondering on how to install these auxiliary switches (GM Oem P# 23145158) without the GM upfitter diagram. I purchased the Bussmann 15303 - 5 it is a weather tight fused and relay b

I have just successfully fully integrated my AUX switches OEM style. My fuse block did not come with the relays or fuses, nor did it have connectors for them. I had to purchase a few new things.

Here are some pictures of the modified buttons. I had to remove all the black and white, then respray the white because you couldn't see the icon in the daylight. I am pretty happy with the way they

Just get them out to the engine bay so you don't have to take the dash apart again when you have more items to wire.

I read this whole thread and didn't see anything about this. My truck just has 2 switches (Traction Control and Bed lights). I'm wondering if anyone has bought a set of switches that includes the pedals button and used that to control something?

 

I'm understand that the switch banks with the pedals have the momentary switches and would need latching relays if I wanted the items to stay on. 

 

My thought is to use the pedals switch to wire to some solenoids to raise and lower my rear air bags. In this scenario it would actually be better to be momentary.

 

Any thoughts?

 

Edit: Obviously I don't have electronic movable pedals so I don't have a use for that switch.

I have a 2019 International CV which is the same thing as a new Silverado 4500-6500HD. The 2WD versions have rear airbag suspension which can be raised and lowered. I’ll see if there’s a part number I can grab next time I’m at the wrecker builder’s shop. (Mainly for the button). 

 

Yes, the pedal adjustment has two different outputs. Since the pedals cannot be adjusted while in gear it would be a great switch to use for something, even momentarily like an air horn.

This looks like a lot of technical work. I have a 2016 will 3 switches now. Traction control cargo light and engine brake. I want to go with the 7 switch you showed in this post. Does each switch have its own plug or is a group one plug system?

I thought the same about air ride and looked very hard at the wiring and it can be done. I would like to see what you end up doing

earlier in this blog there is a picture of the switch that has the three buttons and the extra buttons. I got mine from GM and it was a direct plug and play for my trucks options and I wired in the other switches to the fuse box. but you could go directly to relay. just remember that the switches supply ground and not power.

Thanks that is exactly the switches I need. Went the the GMC shop and asked them for this bank of switches and they could not look up anything without a vin for a vehicle with the right switch bank. Not like the old days when a parts guy knew his parts.

I've been digging through this and a few others as I look to do this mod. Haven't ever wired additional stuff to a truck so this world is new to me.

 

My truck is a 2016 Sierra SLE. I've currently got two switches, TC and bed lights. I'm looking to upgrade to switch bank #23145158. When I popped my box I see the below: (rotated 90° counter-clockwise, so the bottom right is actually the bottom left of the box. Said another way this should be terminal 1 assuming that terminal 1 is the most bottom left terminal)

Looking at the GM upfitter bulliten (https://www.gmupfitter.com/files/media/photo/604/UI Bulletin_110h.pdf) it seems that I need #1, 4, 14, 20:

So, if I'm following this correctly. I buy the new bank, which is plug and play, then run my wires to the battery (red and black to red and black) and run my output wire (prob blue) to pin 1, 4, 14, or 20 (depending on which switch I want to operate which set of lights).

 

I'm gonna need to install some sort of fuse block for a more clean install. Still debating if I want to run a second battery but for the time being I can run this and upgrade to a second battery later if this ever becomes a problem.

 

Can someone correct me if I'm wrong here, noobie and all. Much appreciate the help!

That would be awesome! I looked into it but I can't seem to find parts without a commercial account.

Okay so I’ve read through this whole thread twice now and I still have a few questions. My truck (2014 LT) came with just the traction control and cargo lights, it does not have the relays in the X50. Can I just wire into the harness behind the switches to enable them to work?

I’m still not sure. Myself. The post was not as clear as I need.

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

      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

      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
