    Replaced cig lighter with 12V USB voltmeter and charger

    Thought I'd share a small project that was fairly easy to do below and looks factory.

    • Purchased a $15.00 YONHAN brand Quick Charge 3.0 Dual USB Car Charger with Voltmeter: The charger seems well made, with a metal housing and on/off switch.
    • Removed the radio trim panel (with the help of posts here)
    • Removed the cigarette lighter and wire clip to the wire harness
    • Disconnected the green and red wires to the small bulb that lights up the cigarette lighter- decided to "delete" this so I took the bulb out, taped the socket off, and totally remove it from the cig light housing

    • Connected the van wire harness red/black to the solid red of the 12V voltmeter/charger
    • Connected the van wire harness black/red to the solid black of the 12V voltmeter/charger
    • Drilled the cig lighter hole a bit larger and grinded off the two tabs behind the trim panel

    Sorry, the photos are a bit glary as the blue LED display is bright- in a dark garage. There are two USB 3.0 charger sockets with above and below the display. The USB 12V charger/voltmeter has a cap with a window- I ended up cutting it out, but using the the round back part as a washer between the mounting of the charger and into the hole so it grips better and less likely to loosen over time. There is a round threaded ring the secures it in place.

    I used solder and heat shrink to secure the connections ad pushed the wires behind the dash for a clean look, reusing the factory wire harness. The wires that come with the USB charger/voltmeter are long, so I had to trim and strip them On the heat shrink, remember to insert the heatshrink tube on one end before you solder the connections (lesson learned!).
