ZT-T Rear Seat Backs

[Confucian]

Hi All
Can anyone tell me how to remove the rear folding seat backs on my ZT-T ?. I'm despartley trying to locate the connectors for the rear ADS Sensors which I assume must be somwhere behind the rear seats and under the rear load floor. I have removed the thre bolts from the centre hinge but this dosn't provide enough "slack" to get the side hinge pins out of the body. by the metal tang on the outer ends of the side pins I assume they must be folded down but I can't work out what to do next !!!!!!
