Hooking up heated seat

I installed leathers seats and door panels in my car this past summer and I didnt get the harness from the car I pulled them out of for the driver heated seat. I have the switch although its just a dumy switch for now. Is there an easy way to wire up the switch to the original harness that is there. My car is a 2002 GT and the seats are from a 01-03 GP. Im quite handy when it comes to wiring things up so just wondering if i can just wire the switch up to the seat, power, and ground like Ive seen in the schematics.There have been quite a few extremely cold days up here in Canada and with no heated seats with them being leather seats compared to cloth (which is all Ive owned before) its quite a bit colder on the butt. Any information is appreciated. Thanks

I believe you need the wiring sub-harness that plugs in to the connector under the seat and the switch and wiring sub-harness that goes with it under the center console. you may be able to rig something up going off of a wiring diagram because main harness has all the wires for it but the small (sub) harnesses that plug into the main harness do not have the connectors for options the car didnt come with.
