Hoyt Glagwell

I have a 2022 HD2500, production date 9/21, after reviewing this thread and realizing nothing pertains to a 2500HD , and the wire leads are not needed for a 2500HD, I installed the footwell lights to circuit 157 , the dome lamp circuit in the BCM. The connector is in the BCM in the first slot closest to the OBD11 plug on the drivers kickpanel under the dash, the only thing you might need to remove to gain access is the drivers underdash cover, if your vehicle is equipped with one, the connector is translucent white or opaque in color. There is already a grey wire in slot 23 of the connector. This was my cure for the connection without cutting the factory harness, I took a small paper clip, cut a 3/4 inch straight piece off it , soldered a small gauge wire to one end , then I pushed the metal end of the clip into the backside (wire side ) of slot 23 on connecter X1, I saw how far it went into the connector, then removed it and put shrink sleeve over the solder joint and the remaining exposed part of the metal end . I reinserted the solid wire end into slot 23 from the backside and pushed the connector back into the BCM , then I pushed slightly firmer on the solid wire/soldered wire until I felt slight resistance as it seated in the connector slot 23, and then tie wrapped the wire to the harness covered in cloth, then I soldered the positive leads of the footwell lights to loose end of the pigtail I inserted into slot 23. I now have footwell lights on the driver and passenger side footwell. Section 7 - page 322-323 of the upfitter link shows the proper cavity for slot 23, pay attention to the divider slot on the bottom row of the connector so you are connecting into slot 23, the gray wire, circuit 157. I have pics but have no idea how to upload them into my post. https://www.gmupfitter.com/wp-content/uploads/2021/10/22_Silverado_2500_3500_Electrical_Body_Builder_SM_en_US_2021OCT28.pdf lights used : https://www.amazon.com/dp/B09F9KZXZG?ref=ppx_yo2ov_dt_b_product_details&th=1 one per side , I undersize drilled the holes just to the left of the obd11 connector on the plastice flange of the dashboard , then pressed the light into the undersize hole and it grips it tight. On the passenger side I drilled the hole in about 1.5 inches over from the fuse cover on the same flange area as I did the drivers side. With the holes towards the outside of the dash, close to the door jamb, the footwell light illuminates the side step area for getting in and out of the vehicle. if you take a 14 gauge wire you can feed it between the firewall insulation and airbox to the right side of the gas pedal, then tape a smaller guage wire onto that wire and pull it thru to get a wire from the left foot well to the right footwell. For grounding, I did pull off the rocker trim and kickpanel trim and there is a 6mm stud and 10mm nut that have grounds on them already, I connected the ground for each light to the stud on each side under the kickpanel trim. No idea why the pics have yellow halos around the footwell lights , they match the dome light color in real life .

Has anyone found a simple screw on tpms valve stem cap like the aftermarket uses that registers with the onboard system ?

I installed a set of factory power boards from an Escalade on my 16 HD bonus cab

I did get a set of Escalade running boards to work on my 16 HD double cab.

those aren't the same trucks ....look at em...stickers on lower left windshields, the newer grill has no steps...factory 2500 rollbar...
