Furrion cameras no power?

[t-smith]

I just picked up a Vision S 3 camera system for my brand new Shasta Phoenix that’s prepped for it.

I’ve installed all 3 cameras easily. But I don’t think they are getting power? I think they are supposed to have a blue light that indicates power. None show up on the monitor and none of them have any light.

Markers lights on trailer are illuminated and the cameras get power from there. So I’m not sure if I have bad cameras, or if something is wrong with the factory prep marker lights.

Which pins on the 4 pin factory prep connector are 12v and gnd?
