Yes, I did this with my GP. It was very easy.
Yes, your right the heated seat does have its own fuse...it should be labeled "HSEAT/LUM" meaning heated seat/lumbar. If you have this fuse in your fuse block your car should have the wiring for your heated seat.
Look under your seat on the connector. There should be 2 orange, 2 black, a pink and a blue wire on the car harness...not the seat harness...theres a freakin ton of wires on the seat harness...at least on mine there is. Anyway if you have those wires i listed on the car harness you should be good to go.
Honestly I think every car is setup with the wiring in there because it's part of the main harness...the harness with the switch in it is a pigtail that comes off of the main harness.
Just check it out on your car, theres no way for me to know if its on your car lol.
