- 2023 CX-50 PPT
I wanted to carry over my Blackvue 900X Plus dashcam from my CX-5. The X and X Plus series require 3 wire connection (ground, battery and switched). The switched is required to put the cam into "Parking Mode" when the ignition is turned off and where these cams themselves actively monitor battery level and shut off if voltage drops too low.
After testing, I realized that the CX-50 is like the current CX-30 and I think also Mazda3 vehicles where there are no actual switched fuses in the interior box.
There are a couple of solutions CX-30 owners have used but none appeal to me that much--running the switched power cam wire to the engine fuse box or tapping into the front USB ports (I'm assuming like the CX-30's our USBs shut off after 5-6 minutes post-ignition off). Some have also used OBD2 power-only adapters that have a switch for always on/accessory which shuts off after X time, but that would be a rather messy install with some wiring going neatly to the interior fuse box and then the OBD connector for the switched wire.
I'm going to think about this further and see what the best solution for me might be, but I don't want to wait too long as where I live is notorious for bad drivers and a lot of hit and run scenarios.
EDTI: I also now see some M3 owners have tapped into a harness in the A pillar which has all 3 types of wiring required, but will need to check the CX-50 wiring diagrams to see if it has something similar. Some of the Mazda OEM Dimming and Homelink mirrors when installed as an accessory also tap into that same pillar connector or into existing sensor wires behind the base mirror. That seems to me like the best solution if possible.
