so my problem is i have a dx and i dont know how many o2 sensors im suppose to run i have one before the cat and the cat that i am using has a hole for the o2 sensor but i dont see a plug . HELP PLEASE
Depending on what OBD engine you got + harness you could only have an engine harness supporting one O2 sensor insted of 2 which your DX harness orignaly used... just an idea there
Like serrilion mentioned. It depends if you're running a obd1 ecu which for that case u would only need 1 02 sensor but if your running obd2 which the car should be since its an ek you would need both 02 sensors. If you don't see one Hooke up to the sensor bong by the cat then I suggest you head to your nearest wrecker or junkyard and look for 2 sensors hunts in case u end up using both.
Hope this helps
