O2 sensor wiring?
Post by heavy hitter » https://forums.nicoclub.com/heavy-hitter-u287151.html Sat Jan 19, 2019 4:57 pm
I know the 2 white wires on the rear o2 sensors are the heater wires. But which of the black and grey is positive and negative? As far as I can tell gray might be negative? Anyone know?
