Thanks for the information Robert. To get your Furrion Vision S Camera System item # FOS43TASF working, I recommend the 12V PWM Filter item # VGR64VR. This filter will install behind your Hummingbird's rear backup camera. It's a simple two wire installation that will need to be spliced into the wiring harness.

Your 2023 Ford Bronco has a PWM voltage management system. This system regulates the amount of voltage that is sent through your Bronco's 7-way connector through digital pulses. These pulses are powerful enough to operate the trailer lights but it doesn't send enough voltage to power your Furrion item # FOS43TASF camera system.

The 12V PWM Filter item # VGR64VR has a capacitor built into it that stores up energy, which allows a consistent amount of voltage to be sent to the Furrion item # FOS43TASF camera system.

I linked a couple of installation videos below that will show you how to install the 12V PWM Filter item # VGR64VR.

What kind of camping do you typically do in your 2018 Hummingbird? Feel free to answer this and throw in any other questions you have, where it says Add Comment.
