autogauge afr wiring help
tried to wire up my afr gauge this morning,feed and earth all done,but when i went to wire in the o2 wire on the ecu i hit a snag....have been sent a wiring diagam for a my99 impreza,mine sactually a my00 but not sure if there is any difference,anyways according to the diagram i need pin number 21 on block b136...... but there are no identifying numbers on the wiring blocks,i have a blue,grey and then black block connector into the ecu,all pin holes look wired up the same so i have no clue which wire to tap into....any one help me on this? done a search but not found anything of help,some guys speak of a white wire with silver on it,but that seeems for earlier cars than mine......dont want to mess anything up by wiring it up wrong

as the ecu sits in the footwell blue is at the top,then a gap i think then grey then black at the bottom....so in that case blue would be closest to the engine,anyone else clarify this please
