Where to find fuse for exterior side/back lights?

We are installing some upgrades on a recently purchased 2014 Cedar Creek Silverback 29re.

All of the exterior lights worked before. I installed Furrion Vision S Wireless backup camera and side cameras, the type integrated with a replacement light. I followed the wiring instructions, and am fairy confident I did that correctly. When I tried to test the cameras and see if I could pair them to the monitor, none of them had power (all of the smaller side/back lights, not just the ones I’d re-wired).

I am wondering if the fuse is blown and I need to replace/upgrade it as suggested in the directions. However, I have absolutely no idea where to find the fuse for my exterior side lights. I don't see it in my main interior fuse box or the inline fuses I can see in the pass through or garage. Where should I look? Anyone have a similar experience with the Furrion cameras or my specific RV?

Moved thread from the Tech and Repair section to the Cedar Creek sub-forum since the OP is asking for model-specific information.

On trailers the power for backup (and other) cameras, as well as clearance (side lights), all comes from the tow vehicle. The trailer needs to be plugged into the tow vehicle and if you don't find a fuse for the trailer "running" or tail lights in the tow vehicle fuse panel, look in the owners manual. Often there are multiple fuse panels. For example: On my truck there is a fuse panel in the lower dash "fuses" all the interior accessories and another fuse panel under the hood with about 4 times as many fuses for engine and chassis related items. In addition there are two inline fuse holders the Mfr added to make sure the body control module (BCM) wasn't damaged when trailer wires were shorted.

Before starting your search, check the umbilical chord connector on the tow vehicle to make sure you are getting power where it should be. Most cover flaps have a diagram of which pin is for what. Make sure that with lights on you have 12v at the "tail light" pin.

If no power there, start with owner's manual and if you still cant find fuses for the tow package connections, look under floor mat in front of driver or under dash for any odd inline fuse holders.

Welcome to the forum, I see it is your 1st post!

The Furrion 4 camera OBSERVATION system is a bit of a different animal and there have been several versions. What I'm suggesting is for the last several versions. I don't know the model or version you purchased and you didn't give us that information.

These OBSERVATION systems are wired a bit differently than what typical cameras are wired and TitanMikes information is correct for older systems that got power from the running lights.

These newer systems must have a separate 12v feed for the cameras and a separate 12v feed for the running lights. Typically, the 12v feed for the cameras is fused but always hot. This allows the cameras to be used as OBSERVATION cameras even when not connected to the tow vehicle.

The separate 12v running light feed is just that... a feed from the umbilical cord (and ultimately the 7 pin plug and tow vehicle) to provide voltage for the LED running light part of the camera/light assembly when connected to the tow vehicle and the lights are on.

We're not sure how you connected them so we can't say with certainty what has gone awry but if you look at the manual I'm posting a link to for the OBSERVATION system, on page #32 it clearly spells out the need for a separate 12v feed for the camera(s) (RED wire) and a separate 12v feed from the umbilical cord for the light.(s) (BROWN wire)
