    Bought a 2005 GMC 2500 HD crew cab with snowplow package. It came with a light switch in the cab for installing a amber flasher on roof or on backrack. But no where does it tell you where to wire it to. ANybody know?

    Theres alot of info on this site about this. I recall reading that the wires are taped under the headliner. Most people end up running the wires out the third break light for the beacon or strobe. Someone will respond with exact info for you. Enjoy your new HD

    what ^ said, the wire is up in the headliner and most run it out that 3rd brake line hole.
