A few years ago I upgraded the radio in my 2005 F150 Lariat 2WD to support Android Auto. While I had the dash apart, I removed the factory 12V cigarette outlet, located under the radio in the center stack and replaced it with a dual USB grommet-style port.

I installed a buck converter fast charger behind the dash and wired:

  • One USB lead to the head unit (for Android Auto)

  • One USB port front-and-center for fast charging

It worked great,  but after getting a 3D printer, I knew I wanted to improve the setup.

Two issues pushed this project forward:

  1. Battery Drain – I have a GPS tracker installed, and since I don’t drive the truck often, the battery has died more than once.

  2. No Monitoring or Control – The USB charger was always powered, and I had no easy way to monitor voltage.

So I decided to redesign the center panel to:

  • Add rocker switches

  • Add a voltmeter

  • Add an SAE port for a solar maintainer

  • Allow me to turn off the USB charger and voltmeter completely

Modifications

Because of the depth of the switches and backing hardware, the voltmeter wouldn’t fit inside its original housing. So I:

  • Disassembled the voltmeter

  • Modified the existing STL to accept the bare display module

  • Installed rocker switches to control:

    • USB fast charger

    • Voltmeter

  • Added an SAE quick-connect port to plug in a solar maintainer

Bill of Materials

Already Had

  • SAE Quick Connector Harness
    (Original AliExpress listing no longer available, but similar sidewall SAE panel mounts are easy to find.)
