I would assume thats a Glow shift guage???

You need to drill and tap the intake manifold or use the 1/8" pipe plug on the side of the head. Youll need the 1/8" fitting (and probably a new ferrule). And of course youll need to fix the vacume line that you incorrectly teed into.

This should help:

wow im glad the directions said to do that ... crap ... fail ... ... thanx ... will do that when i drill my exh to put the prob in -

Its hard to see in the pic but the plug is under one leg of the intake manifold. Easy to find once you know where to look. -

tapping into the vaccum line will only measure vaccum not boost. -

Yeah, the guage needs to go the other way if youre measuring Vacuume. -
