Disco 2 AWR 5160 - Seat Heater Control Module

Is there a way to test this off the vehicle?

I bought it ages ago when I was going to activate the heated seats in my D2 until I found out that my seats don't actually have the heater elements fitted

Although I bought it as a working module, I've got no way of knowing that is the case so before I flog it it'd be good to know that it works or not.

It migh be complicated to check it unconnected to the whole circuit cos it needs the heater's and NTC sensor's resistance to be "triggered"

Thanks SF, that's what I thought.
