Same power running boards 1500 & 2500?

[Heath Stripling]

I just bought a ‘20 1500 and my friend has a ‘23 2500. He took his factory running boards off and replaced them with the xxl amp research ones. Will these fit mine? The amp research part number is the same for both. Is mine prewired? Can I add a harness?

I work for the company that makes the GM Articulating Running Boards.  Unfortunately, I design the mechanical portion, not the electrical.  They will fit and if you have an LTZ or a High Country the ARB module is already there, but you do have to go to the dealer for the wiring pig tail and worse the programming to tell your ECM that they are there.  They will probably charge a $150.00 hook up at the dealer.  Sorry that I cannot get you a pigtail but you may find one from a crashed truck, they are the same for all T1XX trucks (2019 to current).  Ebay is my best friend.  K2 and T2 are completely different.  Hope I helped.
