I'm installing a cord for my radar detector. The end
of the cord has a pos and neg. I put the neg on a bolt that is grounded underneath the dash, assuming its actually grounded. Then it wants me to put a 3m connector on a wire gauge 14 through 18, and prefers me to do it on a "switched" circuit. (on when car is on, off when car is off)
I have no clue which wire that would be. Any ideas? Mustang gt 2010

Poke around the fuse box with a test lamp until you find a circuit that comes on when the key is on. Pull out the fuse and put it back in with the hot wire from the radar detector under it. Easiest way, no splicing wires.
