talked to a tech an he said it is pin number 13 on the ecu an the wire is black an got a pic from another guy off here an the wire in the engine bay is gray. im gonna digg that gray wire out too nite. thanks everybody this is a good jump start.

 

ive got a 1986 toyota pickup 22r 2.4 liter 4x4 when i got it sombodey cut off the oxygen sensor and all the wiring my ? is were is the wire that connects to the o2 sener and what color is it

 

86 22r shouldnt have a O2 sensor..my 87 22r has no O2s its a carburetor.. has no ecm.

BTW this is a 3 year old thread..

 

My 1988 Toyota 4WD has the O2 sensor on the exhaust pipe just before the catalytic converter. The wire goes through to the inside cab and is connected to a plug under the driver's seat. It is also a 4 wire O2 sensor.
