Just want to make sure I can make this work , 2012 3500 ST with manual cloth seats. Just picked up some 5th gen Laramie seats heated and cooled. Question of course is can I get the heat and cool to work? If not properly can I at all? I’m lost trying to find to the right info. Plugs don’t match of course. I bought the dash switches for heat/cool/steering heat but there was no plug coming off the harness to plug it in. Is there any aftermarket controller options or is there a way to make it work? First post here so thank you!!!

There is definitely a way to do it. The big thing comes down to cost. Doing it the proper way is going to cost you as it will involve getting the proper harnesses. You won't find the plugs for the controls on your harness because that trim was never offered with those options. You will need to source a dash harness from a Laramie w/cooled seats or from a Longhorn or Limited. It's also best to check and see if there are specific relays under the dash or in the fuse box in the engine.
