Help installing heated and cooled seats to factory, 2010 truck didn't come with the wiring. Seats came out of a 2010.

[xxxstagexxx]

I have replaced my manual seats with power seats. No issues making that work. The seats have heating and cooling. My truck is not equipped for this, not harness, etc. Looking for help obtaining wiring diagrams, instructions, tools, to connect the heater and cooling using stock RAM dash switches. I have the wire, plugs, dash switches. Just need instructions, etc., and someone to communicate with during the hook up. All help is greatly appreciated. Thank you.
