How Do I Run The 12 Volt Wire To The Battery When Installing Wiring On A 2021 Mazda MX-5 Miata?

Question:

All looks easy on this install except running wire to battery for 12v power. Is there anywhere closer to get power, and how do you run this on a 2021 Miata?

Running the 12 volt power power wire for the Curt # C56300 on your 2021 Mazda Miata can definitely be tricky. This really should be connected to the battery as this will keep the wiring from causing any interference with the vehicle's computers.

With that said, I included an install video we have of this wiring harness being installed on a 2020 Miata that should help the process. What we did was follow the brake lines up to the engine bay and made routing them a lot easier. Following these will definitely be the way to do it.
