Hey guys..about to install my newly acquired hpraid boost gauge. Have been going through the guides on where to tap the electricity from and it mentioned taking it from either the electric windows or the light dimming wheel. The installation instruction that came with the gauge says that i should connect one wire to 12v lighting and the other to 12v ignition switch (+). How come theres 2 different wires to 2 different power source?

With that, would it be right if i tap one from the dimming wheel and the other from the ignition key barrel? As the gauge is the 'black face' type, i would like it to be illuminated when i turn the key and not just when i switch on the headlights. Any suggestions on how to achieve this would be great.

The electric window is a constant live (when ignition is on) or if you only want a light-switched source take it from the lamps behind the centre console.

Edit: always stick an inline fuse in!

I wired mine up to the dash light dimmer switch. Don't know what I've done wrong, but my boost gauge is always lit up, whether the lights are on or not It always comes on with the ignition.
I don't mind it like that though, so haven't investigated further

Thought of the electric windows..but since i'm mounting it on a pillar pod, taking a feed from the electric windows seems miles away! Theresa, has it always been lit up when you wired it to the dimmer switch or has it gone cranky recently and always stayed on? Did you also put a fuse in like what webbo mentioned?

Right, everyone seem to only have 2 wires for their gauges..1 live and 1 ground. So how come mine has 3??

Mine has 3, both switched and perm went to my 12+ from the windows and the neg went to an earth around the fuse area.

It all depends whether you want it lit up all the time or not.

It's always been lit up and no, didn't bother with a fuse

The fuse isn't essential, just good practice

Is your gauge a digital readout?

Webbo, its not digital..just regular analogue.

So does that mean that i should just ignore the 3rd wire?
Heres the diagramme that came with the gauge..

As you want it permanently lit up, try ignoring one of the live wires or you may have to join the two lives together. I dont think you want to take it from the dimmer switch as I think that is only activated with the lights (not sure though).

Probably the easiest thing is to take the feed from the window switch then have a play with the two wires and see what happens!

Right will give that a go Webbo. Thanks for the advice.

Just an update..got the gauge wired up and works perfectly. Hooked it to the electric windows and tried one live wire from the gauge and that didn't work. Tried joining the 2 live wires (orange and red) together to get the feed from the windows and it works! So kudos once again to Webbo for the suggestion.
