Rear heated seats

[jamob]

So after a lot of asking from the kids and an imminent winter road trip, I've ordered some heated seat kits to fit in the rear (2+1) kombi seats.

Anyone done this? Also I was planning on using a piggyback on a spare fuse slot, is this the best way or is there a feed under the front seats for the front heated seats I can tap into?

Any help gratefully received!

Cheers
