92 Civic VX/B18B1 swap - code 41
I have a 92 Honda Civic VX with a B18B1, Im currently using a OBD1 P75 and my problem is the cel lights im throwing particularly code 41. Now here is what gets tricky. I have a O2 sensor down by the header collector and its a 4 wire sensor, but I cant find the plugs to the harness for the life of me, I tried looking up images and had zero luck.
So my question would be, can someone show me what plugs im supposed to be looking for? If I dont have the plugs what are my alternatives? I thought about wiring up the O2 to the ecu directly but I was also curious on what type of wire I should use to splice into the other wires on the?

.:FFS TechNet : OBD1 ECU Pin out Schematics :.
If memory serves correctly, the VX uses a 5 wire O2 sensor. You won't find a direct plug in O2 sensor that'll work with your ECU. You'll need to either replace your harness, or just wire a standard 4 wire O2 sensor into your ECU using the wiring diagram I posted above.

If you want to swap the harness, a 92-95 EX or SI harness should work. You might be able to use an Integra engine harness, since they're both 2 piece harnesses, but I'm not 100% sure on that.
If you just want to wire up the O2 sensor yourself (which is personally what I'd do, unless there are other issues you haven't mentioned), then just 16g wire, some solder, crimps, heat shrink, and corrugated tubing, and you'll be totally fine.

Thanks for the help i just finished wiring it and the code is gone, only thing i have left is a tps sensor and barometric pressure sensor. Any ideas about the last one?

I was looking around and read that the sensor can be be bypassed with a chip, Now Id hate to get another ECU and then get it socket-ed again for a chip.
so my question is can I still use my ECU since its socket-ed already and just get the chip programmed?

I finally sourced a virgin p75 and I hooked my tps sensor back since its been sputtering around 2500prms and at 2900 rpms and I thought maybe it's an unrelated problem from the ECU with the new one I didn't have any CELs but the problem was still there until I disconnected the TPS.
Now I bought a new one but now I think I just may need an adjustments on the positioning of the sensor with a multimeter on the old one since there wasn't a CEL anyone can verify?
