View Full Version : Need help B18c into 94 Civic CX O2 wiring

I recently swaped a B18c into my 94 Civic CX. All the error codes are now gone except I still get the error Code 41 (O2 sensor). I'm using a 95 integra p72 ECU. I've replaced the O2 sensor with a BOSCH universal unit and have checked and re-checked many times all the wires from the O2 harness to the ECU. Here's how it's set-up:

From O2:bosch--- to Harness --- to ECU
Black ---- white/red --- D14
Grey ---- Green/blue --- D22
White --- orange/black --- A6
White --- Yellow/black --- A25

I've even tried switching the two white wire and still no luck. Please let me know what needs to be done to make the O2 work.
