Boost gauge wiring

[S3 TAM]

Morning All,

Just a quicky, does anyone know what fuse to connect the boost gauge wires too?
so it turns on & off when the car does.

Cheers

I normally use the switched ignition live in the back of the head lights switch. Use a test light to pin point the wire you want, then use some strippers to clear a small amount of sheath. Wrap wire around, solder, done. You can also use the earth from the same loom if needs be.
