Sorry I just saw this.
Its fairly easy to do.Youll have to remove the seats and take the leather back.Youll need a pair of hog ring pliers and hog rings.
It will take a couple hours to instal, wire up and mount your switches.
Dont Tap into the power seat wiring.Run it all the way to the fuse box.Save yourself some troubles if you leave the switch on,the power seats have power to them at all times.So if you leave the heaters on,there goes your battery and maybe a fire....
Wire them to a switched power.
If your ever down my way I would be happy to help.
