I would think you might be able to find one of these panels and the wiring harness that could plug directly into your wiring harness.

Most accessories are designed to work best when their power supply is switched. I use a GPS and a dash cam for work and I’m tired of unplugging them every single time. If you have pictures or w diagram, it’s something I can tackle.
