Seat heating wiring connectors

Hello,

I own a 2006 Terracan GLS with leather seats. The car is not fitted with heated seats. However under the seats there are several cables of which 2 are connected I presume one is for the seatbelt connection and one is for the airbag registration. There is a other one that is not connected it has a white connecter on 2 wires could this be the normal standerd seat heating and how can I check this without taking the leather off?

Thanks upfront for any info on this
