i have the chance to buy a leather seat for the drive side of my 15 Fit EX. its heated but I don't need to hook that up. Is this a simple swap?

 

Probably not.

It would take alot of work just to fit the seat in your car.

You would be better off getting leather seat covers.
Check Katzkin leather seat covers.

 

thank you for the suggestion. However, they only sell the seats in sets and I only want the driver's side. Since the leather seat comes with the frame; according to the YouTube video I watched it's pretty straightforward. For reference here is the YouTube link
