ok so I'll cut the red one above the box and connect my pos to it

then black just to any bolt connected to metal ?

and this will apply to any other gauge as I have a space for one more. Im not sure which to get though

any suggestions?

Right that guide says that you can have them working with the dimmer switch but doesn't tell you how.

So your gauge wires will be red positive, black earth so to have them come on with your lights you need the red gauge wire connecting into the red/brown wire that's labeled 'switched live' then the black gauge wire goes to an earth wire or bolted to the body and bob's your uncle.

I want it so They come on with my lights

well either tbh, the easiest

at a quick glance I think they have black and red wires

does this help? as it doesnt help me :lol:

i wired mine into the sidelights at the fusebox.

What colour wires have you got?

Do you want them lit constantly whilst driving or just when you have your lights on?

either wire them to the remote on the sterio or take them to ya ignition barrel that way only works wen sterio is on or ignition, also heard you can put them to the remote for the leccy windows as they only work with ignition

Just bought my cupra and it has a boost gauge under the stereo

the vacuum hose is connected but the power ones aren't

How do I wire them for the back light?
