I have a 05 sierra with only the base of the driver seat electric and no heated seats. It's a southern truck but it's cold up here in Kanuckistan

I have a option to buy the seats that are fully electric on both sides and heated.

I have the buttons to put in the front door panels and they seem to plug in the window switches.

Anyone knows if I'll need to make a harness to make them work or is the wiring already there ready to plug those in?

I dont have access to wiring schematics so I thought I'd ask if someone did that.
