I’ve had my 89 base EF hatchback for awhile and the whole time I’ve had it it hasn’t had an upstream o2 sensor wired in. I rebuilt the engine and I want it to run better so I don’t have to rebuild this d15b1 a second time but I can NOT find a replacement harness plug for the o2 sensor anywhere I’ve been looking and looking and I have a replacement o2 sensor with a connector attached already but I just need to find the harness connector now so I can wire it in and be done with it. Any help on the topic would be greatly appreciated

Cut the stock one off the sensor, connect, solder and shrink wrap both wires with whatever weatherproof connector you want. Personally I kinda like the GM style weatherpack connectors but your results may vary.

 

Shoooot that’s actually so smart idk why I didn’t even think of that but I’m definitely gonna do that tomorrow. I appreciate the reply to the thread, I’ll try to make a reply to the thread tomorrow after I give it a shot but that’s genius
