this is long so pleast bear with me.

i am having trouble finding a source to splice the vacuum line that feeds the boost gauge on a 2004 mystichrome cobra with a kenne bell 2.2L. I spliced into the vacuum line behind the glove compartment and the gauge read nothing. i traced the line through the firewall into the engine bay and discovered that the line that reads vacuum/boost for the stock gauge had been disconnected. the stock boost gauge had been disconnected because the car is running 17lbs of boost on 91 octane. there does not appear to be a port on the kenne bell plenum after the throttle body to tap into. there is a connecter with 2 red vacuum lines attached, as well as one with what appears to be 4 lines that is attached. to let you know the gauge is an Auto Meter 2 1/16 mechanical boost gauge that is being fitted via a preformed cage around the stock instrument cluster. now is there a fitting on the Kenne Bell plenum that i am not seeing or can i tap into one of the currently connected red vacuum lines running off the plenum and the yellow vacuum line that goes behind the glove compartment.

i spent an hour trying to figure this out tonight and i though that someone like neoclassicl(sp) or someone experinced with this would know. thanks for all the help.
