I have no clip on the harness side and im trying to hook up a new O2. I tried checking pinouts, but for some odd reason, the O2 wires from the harness dont have any continuity to the ecu. Im lost for answers right now. Not even power or ground have continuity to anywhere on the ecu.
SR? KA? RB? CA? B16A2? B18C5? 4G63?
oh sorry sr.
S13 Redtop? S13 Blacktop? S14? or S15?
S13 Blacktop Sr.
The three wires are,
signal - white - to the ecu, I don’t remember which pin, it’s different than the redtop, shouldn’t be hard to find,
power - brown/yellow?? or something - it’s used to heat the sensor, it doesn’t go to the ecu, it goes over to one of the two plugs by the battery, you need to wire a 12V power to it.
ground - grounds to the intake manifold - don’t remember colour.
The middle wire on the o2 sensor is the signal to the ecu, i don’t remember if the left or right was power or ground.
