Im trying to install a boost guage on my 04MCS!!


where on earth can a put the vacuum line throught the firewall???

thanks in advance!

 

Driver's side... If the aperature is covered with black tape, peel it off - there's plenty of room for the vacuum line.

 

thanks !

 

I cut a new small hole in the same spot with a exacto knife.

 

If you just peel off the Gorilla Tape sealing the hole there's plenty of extra room in the grommit - I have like a dozen wires and the vacuum line crammed in there. I'd be very careful with a knife there - it's hard to see, it's dark and there are lines/wires already in there that I wouldn't want to nick...

After pushing the line through the grommit, open the driver's side knee bolster and look UP towards the place where the steering column goes through the firewall - your line should be there. Sometimes is slips into the plastic shroud covering the steering column, but it's up there someplace.
