Hello everyone, I just have a quick question regarding the 02 sensor wiring from a B18C Sir-G engine to the ecu. Requires 4 wires. Does anyone know the punch code on the ecu for these wire. I'd search everywhere. thanks.

 

What motor is this going in?

 

it's going into a 93 civic hatch cx

 

CX, thats 1 wire (white) o2 sensor right?

This is what you do, you have a 4 wire o2 from the GSR right? 2 blk, 1 white, 1 grey?

Should look like this:



This is where they go:

black - Heater control - A6 ECU - only wire to run through firewall.
green - O2 ground - splice into one of the black wires that runs to the thermostat housing.
white - O2 signal - use existing sheilded O2 wire to D14
black - heater power - power from C125 (large group of yel/blk wires)
