I put this in the "electrical section, thought I would put it here too.
89 toyota, we've searched everywhere for the last 4 hours, the plug in for the O2 sensor laid on the exhaust and got fried, we have a new sensor but went to wire it up and the instructions are no help, just need to know how the wires match.
the new sensor has a blue, white and 2 black wires
the harness has a pink or white w/ a green stripe wire
brown wire
white w/ a red stripe wire
and a black wire
what goes to what? any help would be greatly apprieciated

 

plz tell me that new sensor is a denso or a ngk with a factory style plug

 

I should give you more info at this point, this was my truck till today, my oldest lad has it now. a year ago we we're on the highway and the plug melted on the exhaust, we hand wired it together to get going again.
fast forward to today, I've decided to let him have the truck and he wants to get it in good running order. I was driving it but it got lousy gas mileage, ran really rich. he did some research on the net and found out to put this sensor in, it is still on the hoist as we speak.
the instructions with the new sensor doesn't give color codes, it's four wires you have to splice in with the "SPECIAL" non resistant connectors. it is a densol. it does not have the factory plug with it, which would do us no good any way because our harness plug is fried and gone. He gave $70 for the sensor.
any help would be great as we have to get this thing off the hoist tomorrow, we're right in the middle of a blizzard and we need this thing on the road now
....it kind of bummed him out that we had to use the old scout to get us home.

 

ahh i see anyways i wouldint know but welcome to yotatech and best of luck

 

thanks for the help anyways... paging all toyota guru's, need help now

 

I'd love to have an old Scout.

 

Well, first off, who ever did the clutch is responsible for this melted connector. Didnt attatch it to the rear crossmember and it blows on the exhaust, and melts.

OK, here ya go!
