Testing seat adjustment motors

[green A8]

I seem to remember that this can be done but have never tried.

I'm just wondering if I can test the adjustment motors in a pair of front seats I've been offered, with them out of the car. The seats owner tells me that I need to connect power to the red two pin connector block. Is this correct I don't want to set the air bags off by accident The seats are Recaro type taken out of a 1998/9 PF S8

Thanks in advance for any help offered
