How do you wire things so they turn on and off with the ignition?

[jonrandom]

Ive got a electronic boost controller and aquamist wired up to the battery but this would mean that they would stay on all the time even if the car is not running.

I was going to just put a 12v switch in the circucit so I could turn them off but is there any way to wire them so they switch on and off with the ignition?

Wire it to your headlight switch

I dont know much about electrics so can you expand on that?

So does that mean they will turn on when I turn the lights on or ignition on and how do you wire them to the lights?

Cheers

Easy enough to sort, pull the light switch out and use a test lamp to find the switched live.

Under the steering wheel, there are two terminals, one yellow, one red, one is switched live, one is permanent, dont know which Is which.

For a decent connection, wire into there.
