Adding Air charge Temp

[Powell]

had a few questions on this. Eventually i'll need to add one to run custom cal. I have a 89 intake that already has it tapped so should i use that for simplicity? OR, i noticed people saying that that location is pretty lowsy spot that the intake temp interferes with the reading of the actual air temp. So which should i do and where would be a better place to tap into if i went that route?

Quick side ques. Do the 91+ already have the wiring needed for the sensor tucked away somewhere or will i have to splice into that #24? (i think it's 24,..I'll double check)
