Schoolboy error

[Wafoo]

Swapped the seats over from cloth standard to leather
All connected up but for some silly reason I managed to disconnect the passengers with the battery connected, so now have the airbag light on my all singing all dancing reset tool says there are no codes but tells me the occupancy sensor and seat belt fastened are off?
The only difference between the new and old seats are the new seats have thier own occupency sensors, everything else has been transposed from the original seat
Is there any way of testing occupency sensor?

If you have fitted facelift seats into a pre facelift you will need one of these.They are about £15 on eBay.

I did a seat swap, the bag light came in a few times when ignition switched on, then cleared itself never to return.
