Does the LS engines coolant temp. sensor put out the same signal as a TBI coolant sensor? I've searched and found that I can use an F-body 3 wire sensor but I'm cheap and was wondering if I can just splice the wire to my guage into the two wire sensor.
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.
