I bought a new Kenwood 348U from best buy today, along with a dash mount kit, speaker cable, and a harness adapter for my vehicle model. I connected each wire from the HU to the harness adapter correctly and then went outside to hook it up, but when I turn the ignition switch the radio will not turn on. I tested the yellow and red wires and they're both powered, so what gives?
Edit: I touched the power control from the stereo to the dimmer wire from the jeep, this caused the stereo to turn on for a couple seconds, and then turn off. The dimmer wire has no effect when the cabin lights are on though
