Just finish building the harness and finding all the wire locations to make the factory articulating running boards work on an LT silverado.  Lots of research and time went into this mod.  They work perfectly and have all the messages in the cluster when operated from the switch inside.

A write up on how to do this and what parts are needed would be nice.

Nice mod.  I use mine to reach into the front of the bed often.

Thanks,  I look forward to that whenever  the tonneau cover is off and I am tying down stuff.

I reached out to the Harness Dr. and sunce he didn't have a harness available I was able to buy the wire, terminals, and connector  bodies for the connections of the step motors and modules.  They use molex 120 series connectors and Yazaki 150 series (i think).

The UBEC had the electric step fuse in it, but the chassis harness didn't have the wiring in it so I added a single 2mm power wire to the black chassis connector that plugs into the bottom of the fuse block.  I had to buy the conn socket terminal (found on digi-key website).  That went into position G6 of the connector.

 

I had to add a wire to connector x138 located a ove the driver inner fender, but below the airbox.  It was a 20 way connector that attaches the chassis harness to the body.  This wire was for the BRS cancel/disable circuit.  My truck was prewired on the body side for the in dash swtich and that wire terminated at x138.  I added the molex 120 series male terminal to the chassis side of the harness.

 

I bought the multi-switch that contained the board switch and outlet switch alomg with one blank.  The multi-switch conne tor was pre-wired and required no mods.

 

The last wire to integrate to the trucks system was the GM low speed LAN data bus wire.  This was tricky because not all trucks have the same options, so you may need to tap in somewhere else on hour particular truck.  I was able to find that the floor harness had the wire located at the driver seat connector.  I had to add a wire to pin 5 location to mate with the floor harness connector.  my truck doesn't have a memeory seat module, so the seat harness has a vacant socket on the sear side and the GM Low LAN on the other.  That connector is an ergo-mate 55 way by Aptive / delphi.  

 

Besides that it was a matter of connecting all the board wires to their control module using the factory diagram, and connector end views.

 

I will post more pictures,  and some part numbers for everyone.  Keep in mind that I went the extra mile to integrate it all like factory, but instead of doing terminals like me, you can just clip the wires out of their connecors and connect them to your homemade board harness with butt connectors, for the GM Low LAN and cancel switch.  You can also add the power wire directly to the power post on the fuse block and add an inline fuse.  (lots of options)  I am very ****** rententive with wiring and as a former GM Shop Foreman I have the knowledge of how to disassemble all the connectors and where to put everything.  I tried to rout everything cleanly under the truck as well.

It cost 800 for the boards on Offerup, 100 for connectors and wires, 40 in terminals, 50 in splitloom.

Do you have a list of the plugs and wires you used for the power steps? I just got a set and I’m trying to figure out how to install/ wire them. I’m finding bits and pieces but if you had something showing what you connected to and the plugs you used that would be amazing. Also you mentioned your truck having one of the plugs? Where was that plug located on the truck? I’ve been looking mine over and I’m probably not looking in the right places.

      Well one of our most reliable vehicles was sold yesterday. The first and only I gave for free to a grandkid. If they got skin in the game they take care of it. My wife bought new. Five years later my daughter got it to use. We got it back and gave it to our grandson after graduation. He did zero maintenance just oil changes. When the AC quit he drove his mother’s car rather than get it fixed. Instead he just bought a beater and sold the Elantra.

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.
