Chris:
1- battery heaters (originally 2011 Leafs have a 3rd battery connector for this 
but apparently since 2012 the battery heaters are controlled by the LBC temp 
measurement and then engaging a small contactor to send the HV to the heaters 
internally, so no 3rd connector and external relay, which makes the battery 
indistinguishable as whether it has heaters, other than from the part nr. 
Apparently also the LBC programming is different)

2- seat heaters
3- steering wheel heater
Hope this clarifies,
Cor
