Can anybody tell me how to connect a autometer a/f gauge to my O2 sensor from a 91 civic hb. autometers site shows a 2 wire cnnection and I have a single wire.
thanks for all help

just splice the signal wire from your meter to that one wire on the o2 sensor, be sure to do it before any connections, as close to the sensor you can get. also make sure your ground wire goes to the block if possible

or you can connect the black wire to ground anywhere on the frame, and make the connection for the O2 sensor (purple) signal wire to the ecu Should be pin C16.
