Swap out seats

WesternMike · January 26, 2017

Is this what you are referring to? http://www.gm-trucks.com/forums/topic/196372-sport-bar-pros-and-cons If so, then I think you can get a better price.

Sorry, no. This is what I mean when I say chase rack. I would add the spare tire to top, along with the light bars all around if I do go with this option. But can't make up my mind for the life of me.

Can you confirm how you know they will work?

A local guy has power leather seats working in a Reg cab WT...I do know he did wire off of the bcm for power function. His WT has retrofitted steering wheel with controls, leather power seats with console and signal mirrors. Not sure if his WT came with OE power window and locks..but he has them as well.

Sorry I meant I have a WT2 so I already have power seats and such. This is why I'm thinking it will be plug and play. The seats I'm getting also have everything I need for heated seats to work, so I'll even grab bezel for the dash with buttons then have someone flash my bcm when I get all the new addons I plan to put in it. This way it's only flashed once.

I'm hoping it all works out!

Should be plug and play if you have the electric seats, at least for the driver. Did the WT2 come with the electric passenger? You can wire power to them and get everything to work, including the heaters, just not using the stock equipment as all of that is normally powered/controlled through the BCM. I am working on doing the same thing on a WT with manual seats and utilizing the stock push buttons for control but will be doing it all with custom wiring. Sounds like you got a hell of a deal on them!

So glad to hear someone else on here doing this as well. Driver side is good and passenger doesn't have power now that I think of it. I'll just have to figure out the power for that one.

I'll for sure make use out of heated seats as well.

Yeah $1000 CAD for all seats in crew cab as well as the console, in jet black leather to match my truck. But I plan to knock Him down to $800 lol

Now that is sharp! It wouldn't work for me because of parkades and ferries!

Western...you are right about plug and play. You have the existing wiring for power seats....so drop the new seats and go. The heating function will require some improvising. I too would try to use the oe switch panel. Keep us updated on how you got the heated seating resolved.

Good luck

Should be good to just grab it from the driver seat since it isn't the memory seat setup. Might just have to do some tapping and splicing. Make sure and check the upfitter guide for the truck (Use the 15 model, it is more in depth than the 14 and I am guessing the stuff for the seats are the same). Just at a glance I can see that the seat heaters are provided power then the BCM is controlled by the switches over the serial link which then provides ground switching legs for the seat heaters via the seat heater control module. The seat controls themselves are not ran through the BCM on this setup unless you have option code A45 (Page 167), the passenger is even more simple of a wiring job (Page 169), but I wouldn't worry about tying it back to the stock location, I would just run it over to the terminals located on page 167. Page 888 will show you the seat heater circuits, just work without the module, you'll see you are supplying power on the top of the diagram and ground on the bottom. Just tie those to a switch and you should have heated seats, just going to always be on high as I am guessing the seat heater control module regulates voltage to get the lower settings, unfortunately it is controlled by the BCM so would require custom programming to get it operational in your truck.

Thank you for this!! I have a guy who does all my custom wiring work that's one of 4 guys in Canada for what he can do. What my plan of action is to have them wired like you said but wired into the actual switch that comes with them in the dash as their on and off.

I'm sure he can do this for me to give the appearance of the original feature and it gives the dash that little extra around that blank area on each side.

This will come down to the cost he will charge at the end of the day haha if it's within budget it's a go.. if not it will be two basic switches somewhere.

But I can even get the front bezel out of the truck with the switches.. I just don't know if the wiring is in place behind the dash for the WT2's that would connect to BCM. If it is, then I'm golden as I'm sure I could find someone to do the programming.

I'm going to try to post videos for each install I plan to do. Go over to the Custom Builds section and follow along with the Post I'll be using to blog it man!

This was the member I knew that could provide some direction on this topic. I remember reading your posts on the steering wheel controls, radio upgrades, etc. You kept saying the "MOST" bus... and now know what you mean.

I'll dig into the switch operation tomorrow more. It might be possible to use the switches with the seat heater control module without the BCM. But I don't have either to test, I do know the switches are on the low speed network so I'm guessing they don't work like normal dry contact switches but now you've got me intrigued. May have to order a set to play with. I'll update you if I figure anything out.

So if you're intrigued, I'm intrigued too

.

My truck is a 2016 LT. Came with leather heated, but Manual Seats. I'll explore the X310 connector on the passenger side. So would this be a possible Plug and Play for me? I don't have A45 Seat Memory and it looks like I may just need the power seats and the harness that plugs into the X310 connector.

WesternMike · January 27, 2017

I'm hoping it's possible.

Do you guys happen to know if the wiring in the dash is there already for the switches for the heated seats in a WT2? I took the bezel off and can't see any in the cut outs; but it may be behind the radio. I just don't have access to my truck for another few days.
