Boost Gauge Confusion?! Need advise!!

[cullygti]

Cheers for advice! One more thing, i have a smoked face boost gauge so it only shows with the backlight on. Can i still tap into the dimmer light or will it only work when the lights are on?

yes mate you can tap into that ...thats what i have done and yes again will only worjk when lights are on

Hmm.. Need a line which comes on with the ignition?! Any ideas other than the radio? Wires a bit short so need something near the a pillar?

Or extend the wires 

Only thing not doing it on dimmer is if its too bright it might annoy you at night

If you go behind your fuse panel, there should be a few thick yellow/black wires, they're ignition switched. Ive got my sat nav tucked behind the dash and tapped into them so there's no wires hanging about.

one of the wires to the headlight switch is ignition live, can't remember the colour though

Well I've been trying to do this for the last half hour and have failed massively  !!! For the life of me i can't find how to get the boost pipe into the cabin without drilling a hole through?! I know all the guides say put it through this or that gromit but i can see f**k all that looks gromitish?!? Tried following a few electric cables but no luck just seems to get stuck somewhere!
Fuming, i hate it when i cant do something  reckon a trip to the garage is my only way

Where abouts are you??

I ended up runnin it down where the bonnet pull is

I've given up for today! In in beckenham area (if that's what you meant?)

I looked at the bonnet pull line but again once it goes out of site just gets stuck?!
Done bit of research this grommet that loads put it through is only free if the car is not cable throttle which mine is so theres no free grommet to go through.

The drill keeps coming to mind

I have a 3 wire boost gauge but found I only needed to use 2 wires,
One was the earth and the other onto the light switch,
It dims as it should and works as it should, I cut the other wire off

[Wazzzer]

the other wire you cut off dims the LED when you turn the lights on
