Default B16A O2 sensor wires?

Question, I have a 91 CRX Si with a B16A swap, when I got the car, it had a header, with one oxygen sensor in the colector pipe.

I know that the JDM stock exhaust manifolds come with 2 oxy sensors, so I got a JDM manifold, and 2 oxygen sensors, now I need to know how to wire them?

Since I only know where one oxygen sensor wire is, what do I do?

Can anoyone help me out?

Is your car throwing the code for a secondary O2? Which ECU are you running?

hmmmm I just found out today that OBD0 only has one sensor....

So what do I do if I want to run the JDM manifod with 2 sensors?

By the way I have OBD0

Use a bad O2 sensor to plug the second hole, or perhaps buy a wideband setup.

I have 2 good sensors, can I just use the good one to plug the hole?
Or will it mess it up?

The only thing I am worried about is, the manifold sensors are for 2 cylenders each, so I think like 1-3 and 2-4, is that bad if I am just measuring the content from 2 cylenders?

Will it read wrong?

I will do some research on the wideband setup, thanks for the info so far.

Go for wideband and a tune.

I just searched for a OBD0 to OBD1 conversion, and what I would need to do, and it says you convert from Two 1 wire oxygen sensors, to One 4 wire sensor?

I am kinda confused now?

Does anyone know how many OBD0 is suposed to hve?

No, it will be fine. All cylinders should be running reasonably close enough to not make a difference.

Ok, thanks.

I cant seem to find a wire diagram for a OBD0 ECU, I noticed there are a few wires that are not plugged in to the connector , just loose wires... I want to find out what they are, because I have a few codes I need to fix.

So if anyone can send me a link to a diagram that would be awesome.
