im just checkin over my car today cuz im gonna do my first turbo install pretty soon, and everything is lookin good. but how the hell do i get the wires (or even a thick vacuum hose) through the firewall and into the little "edge" on the bottom of the windshield and the pillar for my boost gauge? pics would definately help, but anything is helpful. thanks in advance.

 

theres a hole where the firewall is..you route it down through the side of the gauge cluster...and through that hole. from that part it is cake. post in forced induction...youll get more answers
