Good Morning,

 

Has anyone attempted to install a power driver seat into a 2014-2015 LT truck that came with a manual seat?

 

I compared the part diagrams for both and the seat harness plug that attaches to the body harness looks the same. I'm just curious if the necessary wires are in the body harness to power the motors on the powered seat.

 

Manual seat:

Power seat:

Any input will be greatly appreciated.

 

Thanks!

Most likely not. You'll have to look at this connector to see if you have the circuits in the seat harness to body harness connector. In the 2016 Upfitter manual, I found a dome light circuit I wanted to tap but the circuit was not in my harness.

Bummer, I was hoping that wasn't the case. You would think it would be more cost effective to not have so many variants of the main body harness.

I agree. However, after looking at all the harness routing diagrams, it makes sense why they have so many variants. Pig tails that come off the main harnesses wouldn't need to be there if the option/Accessory doesn't exist. I think having less part #s and having unneeded pigtails coiled up and tucked away. Less inventory overhead to plan for.

 

If circuits would exist all the way around, make it a programmable BCM upgrade and charge a fee to to upgrade it.

They do this, it's called options when you buy the truck new. LOL

 

I would think you could get power to the seat without any problems running your own wire. I've done it in the NBS and NNBS trucks with no issues, while I haven't looked at the K2xx seats wouldn't think power for the seats has changed, as they have always been power/ground only to run the motor. I will say forget about getting heat to work...

Understood...I was just hoping for that simple plug and play scenario. I'm not interested in the heat option. In South Texas, we need the cool option more than heat. I wouldn't even attempt to get that option to work. I'd just go buy a truck with it.

Good news here is this isn't for my truck. I have power. I'm trying to help out a buddy that wants the change.

 

I'll check my seat harness to confirm the body side connector has more pins than the connector on his truck.

Did you get the seats to work?

The reason why the passenger seat works and the driver doesn’t...

These seats came out of a truck that has Seat Memory. So the power adjust controls all go through the seat memory module.

In order to get the power adjust controls to work, you’ll have to find ALL the power seat control circuits and bypass the seat memory module... and land them directly to the the power adjust switch panel circuit.

The passenger seat doesn’t interface with seat memory and that why it works.

Reading this thread inspired me to replace my manual seats in my 2015 Silverado LS for Power Seats. Only thing is I don’t know how to order the wiring harness. I was told, "There is no simple harness to add for the seats. You cannot even order one. GM orders through the VIN number and you will just keep getting the original harness. The harness in question as the one I replaced in the cab. It runs throughout the cab. This is all to keep people from doing exactly what you want to do. GM wants you to buy a loaded truck from them"

So, I am wondering if anyone here in this forum has a Silverado from '14 to '18 with 10 Ways Power Seats but no Heated and/or Memory seats...if you could share a VIN so I could order the harness based on that VIN....or, advice on how to do this bypassing the GM harness ordering.

In advance, thank you.

Try ordering  the harness without your vin

Thanks Codman67,

Dealer's Parts Dept, request a VIN.

Today, what I'm doing is  looking for used trucks for sale. Some for sales ads, have VINs. Then, I see if they have Power Seats (No heated or Memory seats, just power seats)...then, using those VINs, call a few dealers to see how far I go.

Instead of ordering a harness to bypass the seat memory module equipped in the driver seat assembly you can supply 12v to the red and black wire coming from the seat and it will also do the same thing. Cheap and reasonably simple. I hope this helps I just completed my full conversion in my 17 Silverado.

      Lower trims ( WT, Custom, Silverado ( aka LT )

      By newdude · Posted

      HD at the moment, are kinda their own deal.  How LTZ sells on those vs on 1500, there is a difference.   They are merging most of the mid trims on 1500.  LT, RST and LTZ are replaced by one trim, Silverado.  LT and RST are a BIG portion of sales.    Bad naming choice aside, the new Silverado trim will offer the spread of options that those three trims offered.  So expect to see things like the tech package for example, and memory seats.  And LT Trail Boss will now just be "Trail Boss" (formerly LT Trail Boss) but will offer content spread like the new Silverado trim will.  The press photos showed the Trail Boss (formerly LT Trail Boss) has access to Super Cruise now, which on the current truck was High Country only.       Here is the Trail Boss interior.  Memory seats and Super Cruise are present.  All things the LT Trail Boss it replaces, and the RST it was based on didn't get on the current gen.  You had to go to LTZ or ZR2 for memory seats, and High Country for Super Cruise.

      2021 vs 2026 handling (1500 X31 Sierra)

      By dennismc · Posted

      I installed a Hellwig rear sway bar on my 21 Sierra SLT, it made a huge difference on how the truck handles, no body roll, the trucks much more planted now. Not sure of the suspension differences between the 21 and 26,  if its body roll your having a sway bar will solve it.

      frustrating P0446 code

      By Old Bay · Posted

      So a follow up and my fix. I found in online searches the live data to look at on a scan tool to verify the fuel tank pressure sensor was working.  It showed an spec number towards the lower end of the rang, but in spec.  Then while it was running opened the gas cap and the pressure should change.  It didn't change even a tiny bit.  The data for the purge valve said it was open...never changed. So then I measured the voltages on the plug for the fuel pressure sensor and they matched what it should be.  So local car quest parts had the sensor in stock...it was a bit of a pain to remove and an even bigger one to get it to actually go back in.  It helped to unbolt the driveshaft and bungie cord away from the gas tank to give a bit more room to work. So fuel tank pressure sensor in I cleared the code, and started it up.  I went to the scan tool's live data and... Eureka! The pressure number was different and fluctuated a bit.  So took it on a short drive and pressure number varied saw the purge valve go from closed to open and back to closed.  Drove it to and from work for roughly a week plugged in the scan tool no codes.  I took it in to get tested and passed.  In my state's infinite wisdom (oops meant greed), since I pushed the test with the maximum extensions I have to take it back in by Feb '27 to 'get it back up to date', then my next test won't be until Feb '29.

      loose lug nuts

      By newdude · Posted

      Any grease on the stud threads of any kind?   Wheel studs should have NOTHING on them for proper torquing and so the nuts don't back off.     Are all of the mating surfaces clean?  So wheel, rotor and hub?     We've had plenty of trucks at work with that wheel, this is a first to me.  Makes me think they've got a lube tech putting anti-seize on all the wheel studs or some kind of grease, and they need to stop doing that.  To have 11 other trucks with the same exact problem.

      2027 Chevrolet Silverado: Official Discussion

      By Flynlow · Posted

      I was a Chevy guy for years, then switched to GMC because I liked the looks better.  I'm actually thinking I like the Chevy looks better than GMC for the first time in a lot of years.   One thing I know for certain, the new GMC dash is hideous!  Chevy wins this one!
