I did a bit more research and changed the wiring for the 4x4 indicator light so it is completely off even when the dusk sensor is on. I tapped into the Transfer Case Control Module - which is right above the gas pedal on the firewall. There are three connectors that plug into it. The top connector is the one you want. I pulled that connector out and wire tapped into the yellow/white stripped wire (see photo for exact wire) and connected that to the orange dash LED. I connected the ground from the orange LED to the body. I can report it works perfectly. When in 4x4, the LED is on and when in 2wd it is completely off (no more faint glow at night when the dusk sensor is on). No error codes. The yellow/white wire that I tapped into is the feed for the factory 4x4 indicator in the DIC.
I bought a repair kit from them for $117 - included the twin tube gun, one set of product (twin tubes totaling ~20 oz) and conditioner. I had drilled holes in the bed for a spare tire harness and subsequently relocated it so I wanted to repair the original holes. To repair, I used my angle grinder to grind down some of the original liner around the holes then filled them with JB Weld. I then used the Ultimate Linings kit to repair the liner. Still work in process - just laid it down this afternoon. It cured up quickly (10 minutes, but still tacky). I'll try to post some pics when I finish it up and its fully cured.
I believe it is # 4 in the attached link, but may be # 6. https://www.gmpartscenter.net/auto-parts/2017/gmc/sierra-2500-hd/denali-trim/6-6l-v8-diesel-engine/body-cat/interior-trim-rear-door-scat
Or both!! I put a train horn on with its own button in the center console and an airhorn up front behind the front bumper that is activated by the steering wheel pad. Both are connected up to my onboard air tank. One benefit is the if the alarm goes off, it is loud!
Yes, the dealers have the ability to change the TPMS thresholds. But, it is difficult if not impossible to find one that will do it due to liability concerns. I tried and couldn't find one to change it. I ended up buying a Mongoose Pro interface and a subscription to the GM programming software and did it myself. Very easy to do. The TPMS thresholds are in the BCM module. With the GM software, I have full functionality to program and update all modules in the truck. Interesting though that GM recently added a restriction for the number of times the modules can be re-programmed using the subscription for a specific VIN. I think this is so GM can determine if performance tunes have been dropped in. I think the ECM retains something like 20 or 30 of the last programs dropped in it, so you would have to reflash that many times to clear the performance tune. So, this is GM's way of cracking down I suppose.
Here's a photo of my homemade custom bracket. I'm in the process of priming/painting/undercoating it and will post a pic shortly of the final beast.
Yep - sounds exactly like my predicament although i did have the factory boards and brackets to work with. Never heard back from Westin so I got the angle grinder w/ a cutoff wheel out and modified the factory bracket along with the Westin bracket - Frankenstein'd it!. I had a local guy weld it up for me on Thursday. I need to clean it up and paint it and will post a pic before i throw it on the truck.
I bought the same nerf bars / drop steps for my '17 HD. Purchased directly from Westin a few weeks ago. First off, the installation instructions are just plain wrong. The diagrams and illustrations are inconsistent as it relates to references to part numbers and how & where to install the brackets. To top it off, the brackets are also mis-tabled. It's as if someone purposely put the wrong labels on the brackets to get their jollies. I tossed the instructions and went by the seat of my pants. First thing I did was to pull the factory boards off. No need to drop the DEF tank to remove the two front brackets on the passenger side. As explained in earlier posts, they're a different design than the other factory brackets. Anyway, installation of the driver side Westin board was straight forward. Passenger side not so much. There is no way any of the Westin brackets will fit next to the DEF tank, even if you took it off. I sent a note to Westin customer service to see if there is a different bracket for the HD. Haven't heard back yet. If they don't offer a solution, I believe i can cut up the factory and Westin brackets and weld a custom one together.
