This is exactly what the Furrion adapter does. Just switches the circuit based on a signal on the running light pin. Question - Is this only on trucks with the advanced trailering app? Is the regular towing package ok? I ask as I had camera power problems, got the adapter, didn't make much difference. I found shorted cables behind the running light. Fixed that and the camera works without adapter, but signal is crap. Need to try again with adapter, but wondering if the pwm power could allow camera to work but affect range?
