12v Electrical Mods to JayFlight 264BH

I want to mod my brand Jayflight SLX8 and install some mods to the 12v system.

1) I'd like to install a couple of USB outlets or 12v cigar lighter sockets running off 12v in the bedroom and 1 in the lower bunk. We have 115v power outlets in those areas, but are useless when dry camping.

2) The lights in the bedroom aren't controlled by a light switch, you have to reach up and press the switch in the lights. My wife is a little short and needs a pencil or something to reach the lights. I'd like to install a wall light switch in the bedroom light circuit, but I don't know where the wires run in the wall.

3) I'd like to install a dome light or LED lights in the storage areas, but again, I don't know where to tap into the 12v wires and I don't want to break into the enclosed underbelly.

I know there would be 12v lines to the LED's in the overhead shelf in the bedroom, but I am hesitant to start tapping because I don't know the loads on that circuit.

Ideally I would run a new line from the battery or the converter under the floor and up through the fore and aft storage areas, but it has an enclosed belly and I don't want to put holes in it.

As its a brand new TT, I want to minimize the holes and damage to the walls etc.

Any ideas would be welcome. Much appreciated

My suggestions in red.

1) I'd like to install a couple of USB outlets or 12v cigar lighter sockets running off 12v in the bedroom and 1 in the lower bunk. We have 115v power outlets in those areas, but are useless when dry camping. Since you have lights that aren't controlled by a light switch, you will have 12 volts and ground wires feeding the lights. Easy spot to tie into using 3M Scotchlock connectors. I did the exact same thing and installed a 12 volt power outlet.

2) The lights in the bedroom aren't controlled by a light switch, you have to reach up and press the switch in the lights. My wife is a little short and needs a pencil or something to reach the lights. I'd like to install a wall light switch in the bedroom light circuit, but I don't know where the wires run in the wall. I just yesterday installed a RF remote switch in my rig to be able to turn my inverter off from bed while watching TV. Very easy install. You just would access the light wires and tap in with the little receiver. Then you would have a keychain remote to turn the light on and off. No fishing wires through the wall.

3) I'd like to install a dome light or LED lights in the storage areas, but again, I don't know where to tap into the 12v wires and I don't want to break into the enclosed underbelly. I put some battery powered LED light strips in my storage area. No tap in required. Batteries last a long time.

I attached some pictures of the items I used but there are MANY options available on Amazon.

Welcome Aboard!

I do not have your TT, but I have done almost every one of those mods you mention except adding a light switch. See my signature for a link to the AUX mod.

As for the wall switch, it is going to take some snooping and planning. The light if it is not connected to a wall switch just connected to a hot wire running through the ceiling. It is hard to say what direction it comes from, and what is daisy chained together, before or maybe after it. I would start by turning on every 12V item. Pull the fuses 1 by 1, and figure out what is connected to the bedroom overhead lights. I suspect the headboard lights are daisy chained to that same circuit. In the closets, you might be able to cut a small access panel in the ceiling , so you can chase a new switched wire to the light. A couple more places to snoop to get an idea were the wires are at. Pull the inside AC cover, and the speaker over the sofa. With a good flashlight and maybe a helper you might locate the power feed wire.

Investigate where your 7 pin wire harness enters the TT and the routing of those wires. Jayco typically runs their wires indoors, and not under the floor or in the walls. Looking at your floor plan I do not see how they would accomplish that.

If you choose to run a wire under the TT. I recommend mounting a small diameter PVC electrical conduit or use the braided wire loom to protect the wire(s) from critters and road damage.

I also have a 264BH but haven't done the first 2 mods. However for mod #3, I got several free flashlights from Harbor Freight and mounted them in my storage areas and clothes closets with self-stick Velcro. I also get Harbor Freight's free pack of AAA batteries and change them out a couple of times a year.

The lights and batteries are free, and plenty bright to illuminate the storage areas.

#2. add a pull chain switch like a ceiling fan.

After reading some of the great ideas, I ordered a couple of RF remotes that I can patch into the light circuit so solve my switch issue.

I did find a possible source of power for my USB and 12v outlets. There is what appears to be a relay for the marker and brake/signal lights that is located in the front, driver side of the underbed/pass through storage. The relay seems to have a direct feed from the battery and ground. It looks like the battery feed is 12 gauge but will confirm on closer look. I could tap it and install a fused link which could power my USB and 12v and an underbed light.

I don't know about the impacts on the warranty though.
If I go ahead, I'll take some pictures and post them here.

Thanks everyone for your suggestions.
