At the risk of being ignored for a simplistic question.
I just got a 07 F150 with a pre-installed AVIC D3. I purchased a BOYO - VTL300 License Plate Camera. I a am not sure what power source to tap into use for the red wire. I have heard the reverse lights, but I want to be able to turn on the camera while driving to check on my towed trailer.
Also I Assume the best route to run to the wiring is threw the frame and into the passenger compartment threw the firewall. Ground and RCA plug are understood.
Thanks in advance from a beginner
