Question Toyota '91 4WD SR5 Extra Cab pick up truck wiring question?


I have a Toyota '91 4WD SR5 Extra Cab Pick Up Truck wiring question? The O2 sensor wiring that is mounted under the cross member that holds the maunal transmission in place has a molex connector linking the wiring together. Well, one side of the molex connector is missing & the other is still intact. The problem is that the wire colors don't match up for an easy fix. I would like to know what wire goes where? Is there a site where I can see the schematics of this harness? I don't want to re-wire it up the wrong way? Any help would be greatly appreciated. Thanks...

Get a good wiring diagram from the OEM Toyota manual or

The Toyota dealer should be able to supply you a new connector shell. Inspect the wiring carefully for any damage.

Not sure how similar an '89 is to a '91, but I have a complete '89 toyota 4x4 truck shop manual that I have no use for!
