my question is how do you rewire the o2 sensor i have an h22a engine and im planning on dropping it my 95 civic si so how do change the wiring thnks to everybody
my email prosto-artem@mail.ru
Both your Civic Si and the Prelude H22A have 4 wire 02 sensors.
If you get a 96+ H22 (OBD2) then the ecu will look for 2 02 sensors, but with your car being OBD1, you won't need to hook both up, you'll just need to find a OBD1 P13 ecu, and plug it in.
