Adding heated seats to a 96 E300
 

I recently purchased a 1996 E300. I wasn't very pleased with the stock MBtex seats it came with and located an entire leather interior in the same color with more padding etc. I intalled the new ones and they feel completely different. I'm very pleased with them. As I was looking at the extra harness that came with the seats, I ran the # and found out that the seats are heated. I have no problem with running extra wires etc. What would be the simplest way of hooking these up so they work? Like I said, I have the harness that plugs into the bottom of the seat. Just need to know what else to get. Has anyone done this or rigged it so it works? Thanks!
Update- I also purchased a new wooden console with the heated seat switches and wires out the back of it to tap into. Would a wiring harness be the only thing next that I would need? I found this and looks to complete everything?
