I picked up a set of heated/cooled/power leather seats out of a 2013 longhorn. I got them in and the power works on both seats. (up down forward back..) However I can not find how to get the heaters working or the cooling. I know i need to get power and ground to the seat heaters but i am trying to only tap into the seat harness as i do not want to mess with anything on the truck only the seat. I also have the switches that i can wire up. Does anyone have a diagram of the heated and cooled seats for a 2013 longhorn I can not find them anywhere and the dealer doesnt want to play either

 

I have been looking at doing the same to my truck to upgrade the seats to leather. Other than the heater hook up your are asking .... my question to you is did the seats fit in well and bolt in fine or was there any mods needed?

 

The driver and passenger seat bolt right in. The outside plastic does hit/scrape the door pillar but not much. To fix this you can just heat the seat plastic at the base with a heat gun and push it in a little. Now the jump seat is a different story, the 2013 longhorns seats I got were an automatic so the center consol would of hit the 6spd shifter. So I just cut it and am making brackets and a cover for it. From what I know for the center you will have to make a bracet as there isn't anyway to just bolt it up. The back seats are too wide and the bracket is too long. Again you can just heat up the sides at the base and mold it to fit, and for the bracket it will be needed to be cut lengthwise and new holes drilled. I can send you pictures of what I have done so far when I get back to my truck.

 

Ok thanks for the insights! Sounds like I may be best off by going with some aftermarket custom seat covers.
