hey...I got a civic vx,my o2 sensor was broken so i bought a new one at ebay. But the problem is my old O2 sensor got 5 wieres, and the new one that i got from ebay only got 4,it says on ebay that the o2 sensor should support my Honda civic vx whit d15z1 motor. SO what can i do,should i send it back or rewire the new sensor?
