Firewall grommets and running cables.

[skullx]

Hi Guys,

New to the forum. I've just purchased a 2003 Stock Mitsubishi Turbo Airtrek here in NZ and I am in the process of installing a boost gauge and stereo amplifier. Is their any simple way in these vehicles to get cables etc. through the firewall or best practices for drilling holes in the firewall?

Thanks

There's no easier way. It's hard to reach thru the firewall. My boost. Gauge vacuum pipe actually goes thru the side fender and thru the door sills.

im not sure NZ is a right hand steering or left.. but if a right hand drive, there's a hole near the throttle cable. u may use that hole for boost gauge.. there's a vacuum line at top end of rocker cover, tap the hose for the boost tee..

Thanks for the info. Its a RHD so I'll check out next to the throttle cable when I get a chance. Anyone had any experience fitting the boost gauge where the factory clock is?

Thanks, I'll check that link out.
The boost gauge I brought is a perfect fit in place of the analogue clock on the dash. Just waiting for the glue to dry overnight. Bonus there is power and an illumination wire right their too.

Cool. Do share pictures when done.

I'd like to keep the clock. In fact, the first thing that caught my attention in the cabin was the clock. Feels really classic and in a way, classy. Much like older vintage cars. It's a nice 'watch' to me. :) But yeah, many removed it to mount a display or boost guage there.

 

[skullx]

Thanks, I will do.

I wasn't too keen on removing it either but it was a nice spot and I decided the stereo has a clock instead.

 

[4gbanger]

yeah its actually a strategic spot for boost gauge.. it would look like stock.

When I fitted my boost meter, I just look for the original wiring that needs to come in from engine compartment thru' the firewall. Make small hole, push thru' the tube then seal up....

nice n clean bro.. so tidy it looks like dashborad came with it.. show us picture at dark..

Haven't decided on a colour yet, the gauge will display in blue, green, white or red but the button is on the back. Thinking red to match the dash display.
