Simple answer find a constant switched live

Simple answer find a constant switched live

I can't on that side for some reason it's like there is only power when the lights are on

On the 850 the is a plug under the dash which isnt used and is a constant switched like with ignition I always use that it may be there on the v70 also buy a multimeter there next to nothing and will come in handy for many things

There is a constant switched live on the light switch, I used it on my C70 for my boost gauge, if you want I can go and check what colour wire it is.

Thats probably where it's connected in now so its no use tying to tap into them find one from under dash

From the battery... !!!!

If you take the bottom panel off secured by a couple of torq screws under the wheel find a yellow connector, has quite a few cables to it and approx two inches long.

Within that connector is a permanent live on ignition only, same one I used to wire in a Blitz. Cant remember which pin but its an empty on and all it takes is connecting an earth and try one at a time.

Hope that helps

Normally, any yellow/yellow&black wire is a switched live.

Connect it to the dash light dimmer switch on the live and the guage light will dim with the dash.....unless of course you want it bright all the time!

That would be great if you could mate

Didn't seem to get any power from that one unless the lights were on

One wire from the gauge goes to a black wire on the switch, the other goes to a blue wire.
