what loks to be my second o2 sensor is bolted into the bung but the wires and plug are just sitting there not plugged into anything. wtf. where do they go. i dont see a recpticle for the plug. sorry if this is a little off topic for the allmotor forum but trying to get decent info in the ef forum is like milking a boar or something equally as pointless.

 

my pr3 b16 only has one o2 sensor not 2?

 

Well, the other o2 sensor you have to add, since originally the car only came with one, you need to add wiring for the second o2 sensor, use a connector of your choice. Also it can be very trick wiring the o2 sensors, they need to be flipped and flopped until you have the correct sensor going to the correct ecu pin.

Did you even bother reading the Faq in the beginning of the ef forum? o2 sensors are covered

 

there are like 4 o2 sensors in my dc header. because 2 are in use and the other two are just filling holes. i imagine if you only have one hooked up and the car runs fine then the other is just filling a hole.
