I have a pretty big problem, first i will start off with i have a civic hatch 1994 dx and i have a obd2 b16a2 engine with a type r ecu. My big problem is that i dont have a second O2 sensor wired in. The plug is not their i think because on an obd2a wiring harness i am pretty sure the second O2 senor is on the cars harness and that is not the year of my car. does any know how to help me, or does anyone know how to wire that in.

 

first of all your car is obd1 you dont have a second 02 sensor, and you need an obd 1 ecu, and you dont want to convert your car to obd2 either, search
