Recently changed engine and tranny in my 96 honda civic ,went from d16z6 to d16y8 SOHC V TEC . Now i am getting code from computer for secondary 02 sensor , Which has a different setup from old engine i had in car . Anyone know where i can find wires from engine that go to rear 02 sensor ?? Can i hard wire the secondary 02 sensor ??? Noticed ther is a 4 wire plug under hood near firewall drivers side that was nt on my old harness and nothing going to it think it was two black wires , green , red ???? Could this be for the sensor ??

 

any help with this ??? need car inspected ,this is holding me back , driving with no inspection for like 4 months already . no one has a pinout or rear o2 wire that goes to engine harness ??? for a y8 engine ???

 

i think most Heated o2 sensor sires on our cars are two balck, a green and a white
