Yea you just ground to frame, I usually ground to wherever I’m mounting something. For the switched power there is a new fuse box you mount that has fuses for the switches. Depending on the location of the fuses, they can be either ignition switched or constant power. They are grouped switch 1 and 2 together and 3 and 4 so you could potentially have some stuff constant power and other stuff switched. Pretty slick! 

Hey wondering if you had any issues with the fuses in switched ignition. My upfitter switches work when I have the fuses set on constant. If I have them on switched the relays don’t engage. Wondering if you ran into this and if you have any idea why this might happen. As working fine since I installed them and today it started acting up. Thanks.

For those struggling, I've compiled a Google Doc with all the kits, part numbers and my install process.   https://docs.google.com/document/d/1cudKHwiVgJA549Vl_Dyt6bqa1RRblfEMvxkkEm8c9-s/edi

Installed mine today. Hooked up air compressor for air bags.

I contacted GM upfitter support and got this response a couple months ago:       ImageAndParts.pdf ImageAndParts (1).pdf ImageAndParts (2).pdf

I’m thinking something is defective then. What do you think it could be. The fuse block or the harness that goes from the fuse block to the switches? Just trying to see some opinions on this as the dealership is saying it’s not covered under warranty as I installed it my self

@AdamAT4 You are correct, you are missing the cover connector, it came in the package with mine!

Looking for the Harness (84497098) if anyone has one for sale or know where to get one.  I have all the other parts but that one.

Has anyone put one in a 3.0 Duramax truck?  My kit went in with no issues, with the exception of the cable from the battery to the fuse block.  I know it's probably me, but I swear that my truck does not have the provision for passing the cable through the firewall where the directions state.  It's probably there, but it's buried by a coolant reservoir for the turbocharger, the brake booster, and a couple of large wiring harnesses.  Using a flashlight and inspection mirror, I just don't see that rubber grommet for putting the wire through on the driver's side.  I do have one on the passenger side near the battery, which I think is on all of the trucks, and was considering just going in through there and routing the wire behind the glove box / center console to the connection point on the fuse block.

Tried GM Parts Outlet, got the same response "order cancelled because item is on back-order"

 

Frustrating to have all the parts except one to install the Aux switches.

I see you are in Alabama.  Me too.  I got mine from Bentley GMC in Huntsville.  Their parts department said the part was on backorder, but that there were still ways to get the part.  They got every single piece of the kit for me in two days.  Their number is 256-536-2475.

Mine only has 4 wires, but there's 5 switches

I like how it gives you the snow prep 200A fuse, ill probably use that if I add a winch4183b36c90c3d4cec038d2e8b0a94e53.jpg1d65b035de59cd38357660173e4953d0.jpg

Hey my f block kit is on back order and just wondering if you have any pictures of how you connected the power cable to the battery. I have everything else installed and just wanna get this working.

I just ran my cable to the battery box and connected to the fuse. The secondary fuses that would be part of the snowplow prep kit are also part of the upfitter switch kit.

      Trading 7.3 (Godzilla) for G.M.C gas

      By James Beyer · Posted

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      OCI, not when but why?

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.
