I have installed 2nd. row, heated captains seats in my 2013 Suburban. How do I connect the electrical from the seats to the vehicle? (vehicle originally came with a non-heated 60/40 bench seat). Wondering if the wiring harness has the connectors for the seat heaters and the door controls

 

The controls for the middle row heated seats was located on the back of the front console on my 2010. Not sure what your door controls are. Maybe they changed for the 2013.

 

not sure where the heater controls would be. the front seat heater controls are on the door. do you think the wiring harness is in place and hidden under the carpet or somewhere else?

 

if anything there would have to be a harness IN the center console, then it would have to go to the seats. It's from a computer console, so I don't think it's a simple 12v on/off switch. it's a computer with a relay somewhere else or in some module. May be easiest to install your own 12v with a fuse, and switches somewhere... I don't think the hassle of an OEM look is going to come easy...
