My car is running rich can tell this from black soot on rear bumper,
So got a new lambda sensor, BUT! when i went to remove the old lambda it wasn't connected to anything, previous owner has cut the wirers at the top of the sensor, i have a new sensor to replace and connect up But i have no idea where the wirers connect to, i cant see any electrical connector blocks with nothing connected, and no bare wirers showing, anybody know roughly where about in the engine bay the electrical bit of the lambda connects to?????????

O the car is a 94 impreza wrx

 

im sure there is a plug just under the header tank area that it plugs into
hope this helps

there is one exhaust sensor that plugs in there (un sure what its called)
its the connection for the sensor on the down pipe i cant find
