    No, it will cause the temp sensor to send a messed up signal to the pcm.

    ok, but the 3 wire will work right? I'd rather not run two sensors and $20 for the s&p adaptor is kinda overpriced.

    $20 is cheap if you consider what it takes to make one yourself.

    It would be a hard to find adaptor anywhere else but I think i'm gonna go with the 3-wire sensor. I saw the part numbers posted here somewhere just got to find'em.

    You can use the 3 wire sensor, its from a 98 Camaro/TransAm, but the resistor value inside the sensor is wrong for your dash gauges, it will always be off.

    I'm actually running a 95-98 cluster. Would the resister value be wrong for those guages? If it was to be off would it be off by much?

    Anyone know? I read where nitrous said he used the s&p adapter and his temps. were off by around 12 degrees. Would the readings be of that much using the 3-wire with my guage cluster?
