B18b Eg O2 Sensor Question

[nwisehart]

I am dropping my obd2 b18b in my 1992 civic hatchback right now. on the obd2 engine harness there are 2 different places for 02 sensors. On the front and the rear of the motor. I am running a 2 peice dc 421 header. It only has the insert for the 02 sensor bhind the motor. What should i do? Please help.

Are you going to be running the OBD2 ecu? if so get a bung welded in behind the cat and put the O2 sensor in. Or you can have an emulator used to fake the signal

You should run an OBD1 setup
