How to install boost gauge?

Ok so I went and bought the required gauge I needed. I got the hose I needed. I got hose T's to run the new gauge.

Now this is where the mental retardation kicks in. I cant figure out how the eph to run the hose through the firewall. I dont have a drill atm so that was out of the question for the install at this time. So being that the car had ac and all those goodies. Does anyone know any other ways to install a boost gauge without drilling a hole.

If not possible to not drill a while where is the best spot to drill a hole through the firewall into the car. I can get the little rubber grommets to water proof the hole. But was trying to do this with as little modification as possible. I was also going to mount it in the drivers side vent. Seeing as mine is all sorts of busted out. So if you have any recommendations on where to drill the whole It would be much appreciated I know this is kinda of a noobish question and all but. Well After removing the glove box and trying to slide it down along a plug on the passenger side of the car. Well it was no dice.  

Anyways sorry for the noob thread I did use the search which didnt turn up much answers. Thank you in advance for your help.

Your car had A/C but does not now?

See those two AC threaded ends that protrude through the firewall on the pass side. Remove those, use the holes there. You'll remove the glove box door and bucket. Then remove the duct directly behind the glovebox, unbolt it, remove the A/C thingy, bolt it back together using some sealant, then reassemble everything. Two perfect holes.

Lol the irony of JRaub and Jsvob03 both using the same avatar and both from Ohio.

You can also pass the hose through the grommets where the speedo cable or throttle cable pass through

^^^beat me to it lol

where is the best place on the intake manifold to  tap for a boost guage
dont mean to thread jack but im interested in that info and might help you out

anywhere that has it's vacuum source AFTER the throttle body. If you've deleted your EGR, The vacuum line that went to that it a good candidate. or the FPR, or the BPT... pretty much anything that's after the TB works.
