The subject says it all. I'll looked under the seats of my base model 2013 LR4. There's lots of wiring and some seem to go up into the squab and back. For what it's worth the 25amp fuses for seat heaters are in the fuse box under the hood (positions 8 and 24). I've got the proper environment control panel for heated seats and a nanocom to upload a modified ccf. I don't want to go through this exercise if there are no heat elements in the seats though.
