Just bought an Autometer Air Fuel Ratio Gauge.
Anybody fitted one of these before? If so, could you tell me where you wired it in?
Instructions state the Red wire should go to 5amp fused 12v supply, Black to good engine earth and purple to O2 sensor (is that the one in the downpipe?) According to the bbok these should go into the harness.
Any help gratefully received.
James.
