i have a 96 hatch dx and im using a 96-98 ex engine harness and ive wired up the 2nd 02 sensor. the pins are A5, D13, D14, i cant figure out the last black wire can anybody help i really dont want to break this new motor in with any CEL's its really pissin me off cause i should be able ot figure this simple **** out every which way i wire it i still keep throwin CEL number 65

 

I think one wire has to go to the EVAP purge valve (Ground) on the charcoal canister. I remember doing it to my friends car 2-3 years ago. I'm not positive though. Good luck

 

yeah i tried that one to still threw the CEL

 

bump does anyone have any other ideas on which pin it is

 

one of the black wires goes to the ECU to control the heater. the other goes to ignition power to supply power to it.

 

thanks ill give it a try
