Hey everyone...I'm bringing this thread back to life. I need a little bit of help.
A little update on the car....
90 CRX B18C1 swap w/P28 ecu
So I checked the cel. The only code I'm getting is a 1 for the p28.
I believe that is oxygen content. Which would mean o2 sensor..??

So, here's the Zerg Conversion harness diagram I'm using...
I'm questioning myself as to if I wired these up right. I'm not sure which black wires are o2 heater and or power.
White is signal right???
Green is ground..?
But there's 2 black wires coming from the o2 sensor.
The way I have it wired is:
Red from the conversion harness(power) to one of the blacks and...
Blue from the conversion harness(heater control) to one of the blacks.
So, do I need to just flip flop the red and blue that I pretty much guessed on the two black wires?
Did I put the power to the wrong wire?
I don't know and need help here.
If anyone can help me here to find where I went wrong I would really appreciate it. I think this is all I need to get it running right.
Also the connections are just spun together and taped. This is just temperary.
