I have a 97 civic hx with some random harness and a p2e ecu (DX) and i need to run a secondary o2 sensor. My harness has no plug for it so i guess im left to run all four wires myself. Where do they go?
I was told one runs to a ground, one goes to 12v power, and the other two i have no idea.. any help?

 

did u try searching? i swear i've answered 3 or 4 secondary o2 problems in the last couple days. define "some random harness"

 

its a 98 auto lx harness everything else plugs up.. yea ive been searching..
