2022 Sierra elevation refresh passenger seat upgrade

AliBasha · February 26

Hello, my first post here and I apologize if this was asked or explained before but I couldn't find it anywhere.

I just bought 2022 Sierra elevation the refreshed one and it comes with the power driver seat and manual pass seat.

I want to swap/ upgrade the pass seat to a power seat, all I want is the power function and keep the heated seat don't care about any additional options like cool or memory seat.

All videos or upgrades I seen is for 2022 non refresh and it specify it's not compatible with the refresh one.

I can get a full seat from car yards for $400-500 CAD, for AT4 or denali, I just need to know if anyone done this or whats the steps involved and if need any additional parts/ harnesses.

Thank you

I'd be consulting with @pgamboa the Harness Dr. and see if he has anything available or any insights on this. I know he sells a power passenger conversion harness but its for 19-22 Global A not a 22-current Global B truck.

Honestly, the easiest way is probably to grab a full power passenger seat from a yard, make sure you get the right wiring harness, and check if the BCM needs a quick programming, if you just want power and heated, you shouldn’t need all the extra features.

That’s what I’m trying to do but I can’t find the right harness for 2022 refresh if needed, all I find is 2019 to 2022 non refresh

I tried to contact him but he doesn't accept messages, and I still can't find any possible way or an answer weather it's possible or not.

the seat swap itself is usually straightforward (bolt patterns are generally consistent across the GMT T1 platform), but the wiring is where it gets tricky on the refresh. The refreshed 2022+ Sierra moved to a different body control architecture, which is why older swap guides don't fully apply.
