Ok I am putting a D16Y8 in my car and was wondering..at the time I have a 0ne wire O2 and I am staying obd1 and want to use a 92-95 EX/SI Ecu, well most of these have the 4 wire 02 will this matter if I stay one wire?

 

You will need a 4 wire o2 sensor otherwise you will get a cel for the o2 sensor. The car will run but not as good as if you had the correct O2.

IS there any way to rewire this so I will not have to get a new harness?
