power source from ignition on new truck?

[trouttrooper]

Well, my new patrol rig finally showed up. 2009 GMC 2500HD :thumbsup:

Oh, and no it's not a Dmax. The 6.0 can definitely get up and move when you hit the hammer though. Have to get use to this 6 speed auto, that's a new one for me.

Anyway, I'm trying to find an auxiliary power source that is controlled by the ignition. Meaning it's only on when the key is on. I've used my multimeter on all the empty slots next to the brake pedal and in the little fuse box on the side of the dash. Can't find what I'm looking for.

Do they not give you one anymore?? I've found a few aux power sources but they are always hot.

Thanks

Could you poke around in the fuse box and find what you need and add one of these fuse taps?
