My buddy has an gsr put in on his 1992 cx hatchback and we can't find a way to wire up the o2 sensor. The ecu we use is an ODB1 P-72 ecu. The car primary o2 sensor only has one white wire for the o2 sensor. How do we go about hooking up all four wires for the primary o2 sensor? Any help would be greatly appreciated.

Yup.

 

Wow awesome guys thanks. But I'm a little confuse on the ecu part. Does the ecu pinout he list work on a p72?

 

Wait.... running a 1-wire O2? You won't be able to use the 1-wire with the swap. Do you have a 4-wire O2? Because that will just plug into the GSR engine harness. Unless you don't have the plugs. In that case, you can just hard wire like that thread says. You shouldn't have to do anything else. I didn't do any O2 wiring with mine and have never had a CEL or problem with the O2.
