Right. Had a look at my ecu yesterday. When removing it there was a spare wire that I now know runs to my AFR meter.

anyway the car now runs like a bag of ****e as its came loose and I need some help as to which wire on the ecu it whould be connected to as it seems that before the wire was just stuffed into the ecu. hence its came loose.

 

crappola.

93 wrx import .

best mention that too

 

Also on the AFR meter theres a black a red and a grey wire.

Its the grey wire thats became dislodged from the ECU pin . I'm assuming the grey wire is the one that measures the reading that goes from the lambda to the ECU so I really just need to know which pin on the ECU the lambda sensor signal goes to.
