Anyone know how to get the lights to come on every time the doors open on the 21' factory steps? My lighting will come on when I hit unlock and when I turn the ignition off, but they don't stay on when the doors are open or if the engine is running.

 

thanks!

I see the 2021's are available with power retractable steps.

Does anyone have any info on how these steps mount and tie into the electrical system on a 2020? Opinions on whether to buy the gm steps or an aftermarket step such as the amps?

So along the lines of the original question about how the steps tie into the electrical system I had the same question but more to integrate some lighting features potentially using the wiring from these new power boards.  I have a 2021 SLT without the power boards but interested in the GM part number for the boards (or parts breakdown) so I could look at just ordering the harness.  If I recall the Amp Research board's wiring goes into the cab and interfaces with the OBD.  So with the boards being OEM now, I'm interested in trying to leverage the OEM jumper/interface harness for my custom application.  Anyone have that information?  Thanks.

I inquired about this because I just put a deposit on a truck (still in transit) without the power steps. I was told that they cannot be installed by the dealer because the wiring harness required to tie it into the OBD is not used if you don't have the power steps from the factory.

Not sure how valid this is... Also not sure why you can't just install them without the center stack switch for the carwash...

Had AMP steps on my 2015 Denali 1500 and no problems with them for 5 years. One of the first things I immediately did on the 2500 was ripping off the park benches and going AMP again.

How was the wiring when you switch from the oem to the AMPs? the Amp definitely looks so much better, so was looking into switching out as well.

I haven't read this entire thread.  It probably would've scared me off if I did.  

 

Anyway...  I just got a 2021 3500HD DRW less than a month ago. Put some amp steps on it. The simply plug in to the OBD port. Pretty simple install. Lights come on when doors are open. We finally have more than a few hours of daylight now since summer has arrived so haven't even noticed the lights at night yet.  So Amy Dealer that says they can't be installed can lose out on that money when you install them yourself or go elsewhere.

I don't have experience with AMPs yet but I was referring to the factory power boards. They can't be installed aftermarket (from what I'm told) because there's a switch on the dash to deploy them and they tie into the ECU from the factory.

Hmm well IF that actually is true.  Then I guess GM wants people to purchase aftermarket instead from the dealer or elsewhere if there truck didn't come with them.  I mean i guess thats possible given the fact the general truth nowadays is that if something makes sense it doesn't 

happen and Vise Versa

I’m just curious if the stock wiring can be hacked up and AMP steps used to replace the stock steps. Waiting to see how poorly the stock steps do in the snow this winter before I try though.

Thanks.  Wow.  Look great.  The light is a nice touch.  Those look to be very similar to AMP steps.  Anybody know who for sure if they are or aren't?

I have the GM power steps on my 21 Chevy 2500. I will say that the AMP's extend/retract a lot faster. I find myself stepping on to the GM ones while they're still opening which is a PIA.

      100% agree, there are a lot of variables. I definitely do not drive I’ve like a grandpa but also don’t drive like I stole it. Truck is currently in the shop so I’ll have to get weight later. The price for driving it doesn’t bother me. My precious was a 6.2l so the cost between the two is a wash.

      summer road trips in the 2026 2500HD

      that is pretty awesome MPG there!  I think so far one observation is these trucks do way better on MPG under 65mph vs 70+ and they really suffer at 75+   I noticed on the stretches into NE on 76 and 80 which is posted 75MPH and I was doing 82 I was getting more like 13.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      No ETA is available for that engine at the moment in the GM system.   I would start at the dealer.  Try and talk to the parts manager or service manager and see if they can start a CX Connect case and get an ETA from GM on when engines may be available.  If they just check Parts Workbench and say "no eta", they aren't trying hard enough.  They need to do a CX Connect and chat with DPAC to find the ETA.

      I would have to read back to get a better picture in my mind of some of the other comments and what they were using for a driving scenario they based the fuel mileage off of. That is why the fuel mileage conversation is extremely difficult to make fair comparisons from. If I was to be living in town and only driving around town, light to light and some longer stretches that doesn't have a light every block, and the usual stop at a grocery store and the bank and so on and so forth, my fuel mileage even during the summer time would be so bad with my truck I don't even want to know how bad it would be !. Then add in winter time and idling to warm it up to clear the windows and driving through snowy streets etc, large heavy trucks with gas engines have NEVER been worth crap for fuel mileage and why some little pot licker of a car with wheelbarrow tires and a 1300 cc four cylinder non turbo engine was the ticket to using a mere fraction of the fuel over a full size pickup.    By the way my truck has the 34" tires as its a HC but not the BFG KO3 tires ( that was an option for my truck but the sales guy couldn't figure out what the tires actually were so that never got on the order until it was too late to change the truck order ). So what fuel mileage your getting actually sounds good for "town driving" and with my truck when I go to town the fuel mileage keeps increasing as I get closer to town because it takes quite a while to get the driveline oils warmed up ( and why it always shows better fuel mileage on the return trip from town because its already warmed up ) but once I am in town that fuel mileage average just keeps dropping the more I mess around town and then has to recover back to something reasonable again by the time I get home for an over all average.    I'd be curious what your sticker says for the factory weight of your truck, mine is close around that 7700 lb due to the options it has. But anyway the long and short is, vehicle weight, higher rolling resistance heavy tires and a hefty driveline and a relatively large gas engine make for crap fuel mileage in stop and go scenarios, all one can do is drive it easy off the line at each stop and as my dad had said over the years, drive like a raw egg is under your foot and that's the best one can do. Years back with a carbed engine and if the carb was getting a bit out of tune etc as would the ignition system, the fuel mileage on pickups with larger engines was just awful compared to what your getting. We pay the fuel price penalty for driving HD trucks over some little vehicle, that is the reality.
