Hi every one i have a boost gauge that im wiring up at the mo, it has a live and earth and ignition. Ive got it all working but the boost gauge is continiously lit up from the ignition wire (connected to the turbo timer) even after engine stop etc. Can anyone help me so that it turns off after i turn the engine off? Cheers.

 

I forgot to say its one of those swoosh multi colour ones from Automotive Dials Gauges pods t-piece which need power to light up.

 

wire it into the lights,that what i did with my old one

 

As above try a different live ideally the lights.
