I bought an automotive relay from ebay and you basically wire it through the relay to the battery and earth the relay then splice a wire into a switched circuit (i used the numberplate light) and connect this to the relay there are 3 or 4 tabs on a relay depending on the one you buy here is alink that might help http://www.mp3car.com/the-faq-emporium/1...it-up.html
