2005 Seats - Adding Leather and heat - is there factory wiring I can use?

I will swap out the fronts for a set from 2015 however, my question is would an 2005 have wiring already from the factory that can be repurposed for power connection and also switch integration?

 

No, you would have to run a dedicated circuit and switch/relay/control.
Heated seats weren't even an option until 2012 and even then they were only on Limited models.

 

Thanks for the info.... now hunting for a good kit that has oem style buttons.
