Does anybody know where the intake air temperature is located on my 1991 S-10 Blazer with an 4.3 TBI engine?

I just looked on the emissions application chart in my service manual and I don’t think they used an air temperature sensor on the 4.3Lt Z code TBI engines back in 91.
The way it looks they only started using them on the 4.3Lt W code Vortec engine a couple of years later.
