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.

      Some Assembly is Required

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
