heated seat switches for a 1998 colorado please (and anything else relevant)

[jonnyboy54321]

Have a heated electric leather interior to go into my 1998 Colorado gx lwb.
Apparently the loom for the electric motors is already in all gx's, and so is the loom for the heated seats (true?).
I need a set of heated seat switches, and also any other required parts, such as loom, relays, control units etc if anyone has them please?
Thanks

Does anybody know if these are fitted to any other models? My other LC, a VX, isn't heated, probably as it is an Aussie import (!), I can't find a pic of them anywhere on the net. Thanks
