ok, kinda off topic but deals with the same subject... I have a 96 gt with pacesetter headers, of corce the 96 has 2 front 2 rear o2's... cani just take the connector cut the wires and splice the signal wire into the other 02's signal wire then plug it in to fool the computer into thinking that the other o2 is there?

This works great, I put these in last night. This post should be a stickie or something. For reference, I used the 84 caprice plugs mentioned above. The Bosch part number is 11027. The only way I could tell which wire was correct was to look up the wire colors on the old o2 sensor. On the sensor, two wires will probably be the same color. These will be the heater wires. You want the signal wire so that narrows it down to 2 more. If you were previously using NTK sensors like i was, the signal wire will always be BLACK. So just cut the old sensor off and attach the new single wire to the black wire where the old one was cut off...

1- Is there a difference from obd-1 and obd-II when it comes to wire signals ?
Ihave found that on the Front exhaust manny , the signal wires is the black one ..
2-You mean , Cut the o2 sensor harness ( the one connected to the o2 side itself ) and tap that one wire of the new 02 sensor to the Stock signal wire ??
This seems so Odd though... I mean if it was this easy why didn't they come like this stock ? it would have saved the company tons of money ..N.E.P.O-"The Rebel"

Marc, i think that's what he meant, by the o2 wire harness, sounds like he meant the plug that comes off the o2 itself.
97pgt, they didn't come like this from factory because of air quality regulations. 3 or 4 wires heat up faster cuz they have like an electric heater built in. faster heat up means they can send your ecu correct signals quicker, so you can get the right amount of fuel to burn1996 Boysenberry Probe GT MTXtreme

ok well, what do you do if you sense that the cars wiring harness is jacked up. I mean what if you think the terminals inside are corroded, how would you hook it up then, Just Curious because i tried it only the plastic around the wires, from the cars harness was cut about 1" so i just took the O2, cut its harness off and wrapped it around the exposed part of the cars harnesses wire. when i did this i didnt get a code for a little while, likewise when plugged the O2 in the cars harness i got a code as soon as i turned on the car.

Like Ryan originally said, it takes approx 30 secs for them to warm up. The exhaust stinks of unburnt fuel because the car is running so rich ( testpipe vs cat makes a difference probably). As soon as they warm up, the car runs perfect. I also sprayed for a good couple of miles or more with a 65 wet shot and A/F mixture remained perfect. Altogether, I am happy with a $36 investment as opposed to $65 a piece.

p.s : Thanks, Rypazzzzz.
