View Full Version : Prewired backup camera - no power to camera

I just picked up a 2019 Cougar 26RBS and it came with a prewired mount for a Vision 2 camera. I installed the camera and made sure the power connection was good and tight, but the camera isn't getting any power. If I take the camera and connect it to the power plug on the monitor, it works fine.

It seems like the power line installed at the factory isn't working. I don't know which pin of the 7 pin connector they used, so I can't test for power. All trailer lights, including reverse, all work.

Am I missing something?

Most rear cameras on Keystone are wired to a dedicated 12V line which makes them on all the time. I would check the wires for 12VDC first. What some do is wire the camera to the clearance light that is above the camera mount. That way the camera is only on if the running lights are on.

In the past Keystone has wired the rear camera power to the center running light on the rear of trailers. In order to get power, the trailer has to be hitched to the tow vehicle and the lights have to be turned on.

In a few models Keystone wired a "dedicated circuit" with a fuse located on the main 12 VDC fuse panel in the power distribution center. You might open the power center and see if there is a blank fuse spot that is either unmarked or marked "camera" or some such name.

Let us know what you find as there seems to always be a "new and innovative idea" at the factory ...

I never thought about turning the lights on - I'll bet that's it. I'm not sure that I understand the logic of it, though. Thanks for the help!

Logic is probably just the easiest (cheapest) way to get power.
Pretty sure this is ur problem. Good luck!

From what I have read the camera is wired into the running lights,hope this helps.

They probably didn't want to run the battery down while not being used!:lol::lol::lol: (the real reason is lower cost).

Yup I have 2019 outback 336cg.
Mine is tapped into the running-tail lights.

What was the final outcome? Was it just that you didn't have the running lights on? Was it a fuse in the panel or was it no 12v connection and you have to run over to the center running light to tap?

Yes, the lights have to be on. I guess it’s the only way of having complete on/off control of the camera.

I just got done hooking mine up on a 2021 outback. Keystone didn't hook the wire up on mine. It was there but not hooked to anything. I tied into a wire going to one of the lights.
