where is o2 sensor

[h22bubbleback]

i drilled and welded the o2 bung on....but i cant find the plug on the harness...maybe im lookin in the wrong spot....where the fuck is it??

i use a 4-wire o2 sensor correct?

 

[mwvnos]

plug should be attached to the intake mani support on the back of the engine....

i need a 4 wire o2 sensor right?

 

[mwvnos]

depends on your motor and car....ex/si/dx have 4 wire and vx/cx dont...."dont hold me to that) someone correct me if im wrong...

omg that blows i have a cx harness and bought a 4 wire o2 sensor...neway to convert?

WHT - WHT/RED wire goes to D14 which is O2 Sensor Input
BLK - ORG/BLK wire goes to A6, which is Heater Control
GRN - GRN/WHT wire goes to D22 which is Sensor Ground
BLK - YEL/BLK wire goes to A25 which is Sensor voltage (you can also splice into the power junction harness at the driver side shock tower harness)

but you wouldnt want to do that unless you have the si/ex etc ecu....otherwise it ownt read it....just return the O2 and get the proper one for your car

cx has a 1-wire 02 sensor.

use the amount of wire o2 that your ecu calls for (you don't specify in your post)
