hey guys, im trying to figure out where the disconnect plug for the o2 sensor is on my pickup, 22re, 4X4 manual, you know the rest, haha, the wire from the top of the sensor runs up and into the cap of the truck, got pics to show you, if anybody can help that would be awesome, im guessing its up in the dash somewhere, i dont know

it actually wraps around to the passenger side over the tranny and connects to the wiring harness along with the other sensors on the tranny, then it goes up next to the engine where the knock sensor, oil pressure sender/switch and a few other connect, then the injector wires, a few temp sensors and such, where it is between the two levels of the intake, then wraps around and connects to the fuse box on the passenger side firewall in the engine bay

I'll get some tomorrow. I posted this right before I headed off for work. What exactly do you need though? Just follow the O2 sensor wire to the harness.

oh...actually, weird. Yours does go into the cab. WTH? None of my 22res had that

ohh ok so does the wire go in to the dash area somewhere, i guess i got to hunt it down

update guys, the wire ran right under the driver side seat under the carpet, and the plug is just right there under the seat, thanks for the help, i got 145k miles on the truck, and it has the original o2 sensor, do u think it would be a good idea to go ahead and replace it, its not throwing any codes or anything and is still getting 22mpg, just wanted to know if it would be a good idea to go ahead and replace it with that many miles on it

id say as long as its working and clean leave it on there.

hey Mistery, thanks for the help, i figured it out last night up at the garage, what a dumb design to hide it under the seat, but i guess it keeps the weather away from the plug, so i guess its not so bad after all
