Electrical Adding Factory Heated Seat Option

I am trying to add the factory heated seat option to a 2007 Mustang that did not originally come equipped with heated seatsView attachment 137305. Has anyone managed to add the factory heated seat option? On one of the Mustang forums some time ago, I came across a thread where somebody put together a list of all the parts needed along the part numbers, but can no longer find it.
I picked up on Ebay the HVAC control unit that has the heated seat buttons and also picked up the (4) FordView attachment 137307 heated seat pads. I know there is also a relay and additional wiring harnesses needed. Anybody have part numbers for the relay? Any pictures of what the relay looks like or where it is located?
