Default HAC Sensor?????

Looking through my Supra today and I found an HAC sensor laying around in there. I have a 1JZ-GTE swapped in my 87 mk3. I have no idea what this HAC does, beside altitude pressure or something. Can you guys tell me if the Supra still uses this HAC sensor after a 1JZ swap? If so can you tell me where it is located or supposed to be so I can see if I have one installed?
Thanks!

Oh and by the way I tried to look this up in the searches, but HAC is too short and will not show up any threads

No, the 1JZ shouldn't need the HAC at all AFAIK... isn't it MAP based?

The HAC is essentially a MAP sensor which serves to provide a supplement to the AFM's measurements. It's mounted to the same support that the glove box's hinges are mounted to.

Thank you, I thought as much but was not sure. Definately MAP based.
