We installed one in the cavity next to the Jensen Entertainment Center. We have several 12Volt cell phone chargers that use the outlet. The bezel just pulls off the Jensen, under that is 4 screws. I pulled out the stereo and rested it on a folding table to reduce strain on the wires. Inside there are clearly labeled wires. The Jensen stereo is 12Volt and a convenient place to tap in. I installed an inline 5 Amp fuse.
