ECU pins query, 1992 NA model

i have a 1992 NA SW20, aust delivered. There are 2 pins on the ECU i can match with any wiring diagram I have.
 
pin 8 on 22 pin plug. marked AC2 on circuit board. most likely something to do with air-con. in or out??
 pin 7 on 16 pin plug. marked TT on circuit board. no idea .. (Since found TT in 98 model diagnostics plus, but not in this car. more confusion)
 
both the markings come from the ECU circuit board and have wires attached to the plugs, so they must do something
 
has anyone come across these????
 
thanks, Terry
