which wire is the signal sending wire? i have a 4 wire o2 sensor.

 

Just chuck that thing , its slowing your car down.

 

your a butt. im putting in a air-fuel ratio gage

 

Use a DVOM and check the wires. The four Wires are; O2 sensor output, O2 sensor ground, 12 volt heater feed, and heater ground.

 

right so what color is the o2 output
