I have a impreza 93 wrx import, i fitted a second hand decat pipe from a 96 impreza wrx everything went well until i tried to connect the lambda sensor, the car has 2 wires (black and red) but the new sensor has 3 (1 back 2 white) Does anyone have any ideas as to how to rewire them?

Cant you just use the lambda off the previous downpipe?

No can't use previous sensor as it is too big for the hole in the downpipe.
