diagram for light switch to power gauge

[ThrushMotorsport]

Anyone able to give us a picture of the diagram for the light switch or something to light up my boost gauge? Only want it on when lights are on.

Cheers

1 of the wires on your radio loom will do it as 1 of the wires is on the lights loom.If you take your stereo out turn your lights & put a test light light on the wiring harness plug you`ll find the feed mate.
