my motor swap is complete. i have a check engine light on for the secondary o2 sensor so i get a cat from the guy i got the swap from its a 4 wire o2 and the wires coming off the EWH are 2 wire so how do i do this??
is there a way to wire the 2 wires into the 4 any one got ideas Give me help asap please!!!

 

maybe replace the cat and use the same o2 sensor?

or just replace the 02 sensor made for the car.

 

replace ur o2 sensor with a 2 wire and recheck possibly why mil/check engine light is on .

 

all i can find is a 4 wire no matter what year civic i use v tec or non
so should i just get a universal one and wire it up??? or any links or part numbers

And FYI its the rear o2 sensor the one in the cat (not behind it....)

 

then perhaps best bet to try it out and see what the out come will be theres always a solution to a problem just keep trying . MAY THE FORCE BE WITH YOU . LOL
