Ignition feed ?

Can anyone tell me where to get a live ignition feed from? I fitted a Roadhawk surveilance recorder today and at the moment it's connected to the 12v lighter socket. I could do with hard-wiring it in if anyone can help. Great bit of kit though.
 
You can either piggyback off the cigarette lighter live feed, or piggyback off the radio feed with a relay via the small yellow lead. :tongueout:
