Oxygen Sensor, which one?

[Dirty Harry]

I'm swapping engines on a 92 hb, I'm putting in a D15B VTEC JDM engine. The oxygen sensor on the JDM engine only has one wire and the sensor on the engine I took out has four. I went to a couple of auto parts stores and they all only showed the oxygen sensor with four wires, one guy told me I could use a universal one that only has one wire but it would mess things up. I do have the matching ecu that goes with the engine I'm putting in. Can anybody please help me out and tell me which one I could use?

Thanks

use the one for the engine your putting in... you'll prolly have to order a new one from Japan when u replace it.

would the sensor from a 89-91 civic work? because they are a one wire sensor, the only thing is the plug is different. I'm getting a DC sports header so I will be getting the cable to extend the o2 sensor and that has the 4 wire plug on it. I'd just have to find out what wire I connect. Would that work? If not do you know a site where I can order parts from japan?
thanks for the help

I don't know if it'd work or not, but the '92-'95 CX has a 1-wire O2 sensor. But the 1 wire that you should be using is the white one. But honestly I don't know for sure (not positive), but I'm guessing a CX O2 would work fine.
Also you should PM Exempt, he did the swap in his 4th gen, ask him what O2 he used.

Use the 92-95 CX o2.

This is not true.

92-95(maybe up to 00) CX uses a one wire.
92-95 VX uses a five wire.
DX/EX/Si use a four wire

The number of wires is not indicitive of the OBD generation.
