where on the firewall do you pass the wires and vacume lines = i am passing some through the stearing colum rubber, but it getting tight, any ideas = the whole forewall is all inslutated. going to install bost guage and ps2000. etc etc.

 

Lift the insulation and install hole with a grommet, reglue the insulation after wire installation.

If you have an automatic tranny, you can use the knockout for the clutch linkage.
