Routing Vacuum for in car boost control

[opzWE4]

I installing a bleeder valve in the car to control boost, but I'm not sure where to rout the vacuum line through the firewall. Any suggestions? I'm looking, but not finding anything in a search. Thanks Mike

i put my thru the same hole as my boost oil and temp lines go thru ...but i went to the hardware store and bought some small metal tube and inserted that into the firewall and used gasket sealer around it to keep it in there so it wouldnt kink i then ran it down into the center console using another piece of small metal tube to keep it from being kinked by going under the console i then ran it up closer to the seat and lifted up on the bottom of the console and only stuck the knob out ...i have it set up so that if i turn it forward ..more boost...and when i turn it backwards ...less boost ...the way i have it down you dont have to drill or put any more screw holes in your car

That's sounds like what I want to do, but where is the hole located on the firewall? I'm looking for a place to make a hole in the firewall that is relatively easy to get to.

my hole is to the inside of the brake booster ...it was there when i bought the car ....so i dont know if it came stock like that or not ...but if you have to make one your self its not hard ...just drill with a hole saw and put a rubber grommet in it and then run your lines thru it ... i use black rtv so it somewhat blends in to keep it waterproof

Thanks Wes, that's where I was thinking about drilling. I was also told that it will work at the gromet where the throttle cable goes though.
