Following Graham's point, the black wire to Pin 2 may be wired within the car (ie at the towbar connector) as either aux power or as reverse light power. Obviously you can check this without the van being connected.
So if you plug in the van, turn on the ignition and select reverse, then, one way or the other, pin 2 should be live. If you then remove the dome or cover to one of the van lights (the easiest on ours is the external dome light), you should find power when you toggle all switches in sight!! (especially switches with brown toggles).
