howdy folks, well I am trying to fit up an Autocom system to our bikes, and the manual states: "Connect the red (positive) wire to a recommended, switched ignition, fused supply, such as the positive feed to the taillights, or rear brake light switch and solder the joint." so how do I figure out what wire to connect to? I'm no electrician but could use some help if anyone can point me in the right direction. I can get a test-light or multi-meter but do I simply stcik the pointy end on to a wire and turn on the ignition until the light/meter shows or is there a specific wire that I can tap into? help! PS don't make me resort to asking the Mrs for help!
