Freelander 1 Retro-fit heated seats

I'm just wondering about replacing the seats (fabric knackered) in my hippo and was wondering (if I was lucky enough to find a heated set from a scrapper) whether all the wiring would already be there on my car? Obviously, I don't have the switches fitted, but if the wiring loom / relays /etc are the same for all models, I could maybe just get some switches.

...or would that be a bit too much to hope for?

Some wiring might be there, and what's missing is simple to add.

No wiring to be found on my 2001MY 1.8S 3-dr FL1 To be honest, it is pretty much the only option I miss - although air con would have been nice (and became standard about a year after mine was built according to the interweb...)
