How necessary is the IAT?
In mine (98 d16y
it was in the stock intake pipe, which I just removed, not the IM like on some cars. I'm converting over to obd1 and just wondered if I'm going to have to make a hole in my charge pipes to re-mount this thing. 
I just looked at the pinout, and sure enough, the obd1 has a pin for it also. How important is it to mount this thing, and how did you secure it in your charge piping?

Tuner Ive got a '99 y7,guys told me
to zip tie it to the firewall.The car
didnt exactly run properly.What i did was
extend the wires so i could put it where its
supposed to go,in the tube between the K@N
and the turbo,hence the name Intake Air Temp.
sensor.Not the charge pipes or the intake
because i tried those first.Yours might be
slightly different because mines OBD2B.

so you think it's better to put in in the charge pipes or the intake pipe before the turbo? as far as mounting it, just drill a hole and find a grommet that it will fit snugly in, that's how it was on my cai, and it wasn't really that tight in there, but i never had problems with it.

Bah... stop half assing. Just because it's "homemadeturbo" doesn't mean it "halfassturbo".
Just drill a small hole in your charge pipes for the probe, then two small holes on either side for the screws. Put a bit of silicon around it to seal it. Done deal.
I ran this setup the year I had a SOHC turbo, never had an issue.

Re:How necessary is the IAT?
its not a good idea to put an air temp sensor BEFORE the turbo on a turbo car.
compressing air heats it up and an intercooler won't be able to get rid of all the heat in some cases; and it'll get rid of more heat in other cases.
put it right before the throttle body in your charge pipe.
