obd1 o2 sensor
Any misinformation is too much. When dealing with wiring it can get annoying. And so I offer this thread to assist anyone in wiring a 4 wire o2 sensor.
Image 1 displays how the harness and sensor connect.
Image 2 shows each connector from the front.
Image 3 the back.
Wire Legend
1. SIGNAL
2. GROUND
3. 12V POWER
4. HEATER
Image 4 shows a Honda factory engine harness connector.
1. WHITE = SIGNAL
2. GREEN/WHITE = GROUND
3. YELLOW/BLACK 12V
4. ORANGE/BLACK = HEATER
