Here’s a shot of the wiring diagram from the instructions. For once, I wired the power wires up like they told me to. The red power wire had a connector on it to plug into a switched spot in the fuse block and the black wire had a “fork” on it for ground. It didn’t quite reach the factory ground point under the dash, so I just zipped it in with a self-tapping screw. I didn’t use the brown wire, which is an auxiliary negative to trigger a mute on an aftermarket radio or subwoofer. If you have one of those fancy Jeeps with an amplifier, you might have to install the brain of the interrupt near the amplifier. Because the audio-interrupt interrupts the speaker-level wires, it will work even with those fancy stereos.
