I need to know about the wiring differences between my 95 CX and the integras. I think i need to just add another O2 wire but i am uncertain. Any info/links would be appreciated.

PS sorry if this information is already posted. Please direct me to the said post. Thanks

 

if the b18b is obd-1 than you dont need to wire up anything...just make sure that you use the integra ecu, mounts, and axles

 

actually the O2 sensor in the CX is a single wire so a small bit of wiring is required.
on the new 4 wire O2 sensor there should be a white wire, a green wire and two black wires.
the white wire is the signal...splice it to the single wire that you already have.
the green wire is a "signal ground"...splice it to the GRN/WHT wire from the coolant temp sensor under the distributor.
the black wires are for the heater circuit...
the first (either one)splice to the YLW/BLK (any) at the junction connector near the clutch master cylinder(this is for power)
the second black wire needs to go to PCM connector A6(this is for heater control)

hope this helps

 

is the cx the only model that had the single wire o2?

 

As far as the EG models, yes...that I know of.
The OBD0 models were mostly single wire O2 sensors. OBDI almost all are heated sensors which is what the extra wiring (and codes!) is about.
