Question about 2000 Pontiac Sunfire
You sure you have the right harness you are trying to attach to? Most have 3 or 4 wires. Heater wire, ground, and signal wire. The 4 wire setup has two heater wires. I don't believe they make a two wire o2 connector because it wouldn't have a heating element or signal wire, has to have ground.
