I just helped a buddy swap a b17 into his 90 integra. We got a (pr3?) ecu to run the motor, all that is left is wiring the vtec. I can imagine this topic has been beaten to death but I cant seem to find what I am looking for as far as the wiring and I dont have to to search extensively, So im hoping someone will help without telling me to search.
Anywho, I have the diagrams I need to wire in the pressure switch and the vtec solenoid (3 wires if I remember correctly), but I am unsure when it comes to the o2 sensor wiring.
-Can I use a 1 wire o2? If not, what sensor should I get?
-This o2 needs a bung welded into the header right? Meaning I cant splice into the stock sensor?
-Do I just wire the o2 straight to the ecu?
Thank you for any help in advance.
