tech help on I.D.'ing a sensor
what is the sensor for on the air bridge on the pass. side just behind the mass air flow???? mine has had the wires cut right at the end. my 2000 cpe was purchased with a vortex cold air intake allready installed. i was putting on the red coupler i got from a forum member today and noticed the sensor wires had been hacked off. the sensor has a very small loop that sticks into the air bridge. about a 1\2 inch or maybe slightly longer, with what appears to be some sort of small oblong shaped transistor attaching the loop. is this the nitrous trigger switch i have been dreaming about? 
or just some sort of none important part someone cut off of the original air box?? 
hey and if you think it also should be the nos. stuff i so desire, could you send me the rest of it????? 
thanks for your help identifying this

The earlier maf's were a 3 wire connector and the iat was mounted separately in the airbridge, whereas the later style maf was a 5 wire connector with an integrated iat. A simple visual will tell you what maf is installed on your car.

O.K. If you have a 2 wire iat mounted and connected on the driver side right before the tb, you're ok. The other sensor on the pass side is probably just plugging a hole that someone probably drilled out for a nos spraybar at an earlier time then removed it.

Actually, the location of where the IAT sensor is now, is the original factory location. The other location on the pax side is what looks to me like where the previous owner had installed one of the IAT sensor re-location kits, sold by several vendors. He may have had some sort of issue in the past and decided to go back to the stock set-up.
I agree with Bill, if it's running fine, don't worry.

Looks like someone repaired / plugged it that would be my guess as long as it's not leaking any air there it will probably be ok.-=Rick

The first picture is the MAF plug.
The second is a plug (factory location of the old IAT)
The Third is the new location of the IAT, The aftermarket intake looks like it required it to be moved.
