Snake your three items up to the top, then out of the pillar and under the headliner. There are U-guides inside that pillar made just for wires. Then you can run the vacuum line up to the speaker area by taping the end to a coat hanger.įrom there, the line joins the two wires from the dimmer switch, and you snake those up the A-pillar, whose trim piece comes off with gentle (or not) prying. Take the grille off the speaker, then take the speaker out. The knee bolster area of the dash has a fairly clutter-free zone that extends up to the dash speaker that lives at the base of the A-pillar. Really! It kinks easily, but that doesn't affect the reading unless the kink is not straightened out. The vacuum line that comes with the iPD gauge is very generous, so I was able to go from the vacuum tree, through the firewall, up through the dash and A-pillar, and over to where you see the gauge.
BEST BOOST GAUGE REPLACEMENT EYES POP OUT INSTALL
Assuming you're going to do the headliner install like mine, you'll need a bracket or some random piece of metal to mount and keep the gauge where you want it.I chose the iPD R Boost Gauge ( link to kit). If you choose an unlit one, you don't have to do any electrical wiring, but it won't be illuminated at night. You need a boost gauge, either lit or unlit.how I bent the metal rod to make an attachment anchor for the gauge - and I will fill those in over the next few days. connection of the tube to the vacuum source and 2. There are several bits missing from this tutorial - like the 1. It's slightly nearer to my field of vision than any of the other mounting positions I tried, so my eyes are on the road more. It's there when I need to know boost, and invisible to me all other times. Because it's mounted up high it's unobtrusive, and far less likely to be seen by street racers, cops or thieves.

The end result is a nice-looking, nice-functioning boost gauge that dims with the rest of my 1997 850's instrument gauges. I have an A-pillar gauge holder if anyone wants it. I'm tall so my eyesight is up there anyway. I tried A-Pillar, lower-left dash, and instrument cluster, but found that headliner/rearview mirror was best. To put it simply, it was the best place for me.
