ok... i have a 1994 truck with a 1992 motor swapped in. I know it is running very rich but i do not know where the o2 sensor plugs in. i need help with what ever else will help the motor out. it also seems to fall on itself when giving it some gas in 2nd gear.

 

Isn't the O2 sensor located just before the catalytic converter?

Or are you asking about the wiring harness?

 

yeah i got where the o2 sensor is i just need to know where the wires go to? because i can't find where the sensor connects to.

 

shouldn't the plug be hanging somewhere close to the sensor?

 

when under the truck on the side of the exhaust exit you should be able to reach up about 10 inches forward of the O2 sensor and it should be tucked up in there. I can't remember exactly what it is tucked in between.
Did you remove the original one?

 

long story short. i bought the truck from a kid who had mustang 5.0 headers on it

 

i mainly need to know where the o2 sensor plug come from so i can locate it. pictures would be ideal if possible.
