Well there are a pair of wires in the connector that provide the on/off control to the seat heaters as well as temperature sensor feedback:

Green = Heat on/off
Orange/Green = Temperature Sensor

These wires are fairly narrow gauge (.35 mm diameter). If you see these wires in the seat half of the connector -- I'd guess the seat has heat.


The wires should be on connector pins 2 and 3. The big red/brown power wire is pin 4.
