New PSI switch

I have ordered a new psi switch and was wondering if I could run a short piece of air line to a T fitting to put the switch on. This would give me another port to hook something up in the future without tapping a new hole in the tank? Since my horns have been out of order for a few weeks now I cant wait to get them going again.

i dont think i would T it in the air line but why not put a T fitting in the port on the tank. I have 3 T’s in one port to make 4 ports/ pressure switch/ saftey release valve/pressure guage and quick disconnect
