Boost gauge install

[Rylee]

Hi, I need some help fitting a digital boost gauge on a Leon Cupra mk2. Basically where do the orange and white wires connect to? Does anyone have any photos at all? I want blue in the day and red at night. Thanks

You should only need to fit the red and black for the gauge to work mate
orange is for the dimmer function so if you want that to work it needs to be wired to a source that comes on when the lights are dimmed

Hi, thanks for your reply. Yeah, I found out where the orange one goes haha. I’m just hoping someone knows how to connect the white wire as I think it goes to ignition

sorry mate yes white will go a ignition on source , red to constant 12v I’m assuming to save your settings on the gauge

I’m struggling to find where to connect the white. Is it on the ignition loom? Or is there another way?

The way i fitted mine was using a piggy back fuse connector into the fuse box (side panel ) rather than tapping into the wiring mate , then used a multi-meter to find a ignition on source .
there are two types i think your after a cranking ignition that just wakes the boost gauge up ?

Ohhh so you piggybacked a certain fuse that when you turn ignition it becomes live?

I will take a pic of my setup tomorrow mate and what fuse I tapped into if you like ? , I also wired a resistor in so that the gauge match’s my dash lights at night (no blinding boost gauge when the suns gone down)

Did you take a photo mate? Thanks

Your fuse layout may be different to mine but this is how i have wired mine up mate
this was only to test different resistors , now the wiring is all head shrinked and insulated / connected properly i know it looks super bodge there haha



,

**sorry for the late reply by the way mate the weather was terrible over the weekend **

You want a fuse for your cigarette lighter or USB port, piggy back kits cost a couple of quid, handy for fitting dashcams etc. Cables eaisly hidden too.
