Need a "switched" 12 volt wire

[spdljohn]

I am hard wiring my radar detector in my 2011 F250 diesel and need a "switched" 12 volt wire under the dash so my radar detector turns on and off with the ignition.

I brought mine out of an unused terminal in the fuse block under the dash..
not sure how the 2011 is equipped, though

I'll try to remember to look in the morning. I couldn't find a key on wire. I used a wire that is energized when the key is in the ignition.

Look for the radio fuse and use that wire.

or check the 12v power outlets usually one is switched ,,

Look for the radio fuse and use that wire.

Yep.. thats what I did, but be sure it's the one that powers up the radio.. Key On Only.. not the one that powers the memory presets. (don't ask me how I know that )
