If you have something it would be place for me to start.
I have a 2016 HJ and want to clean up the wiring in the battery compartment.

If you were asking me, I have one from Jayco showing my battery area wiring. I have another diagram that is more specific to my Onan EC-30 generator control system that is much of what I modified this past weekend. I know that newer Senecas have a different Auto-Start system for their generators, not sure when they stopped using the Onan system like on my unit.

Both drawings attached below.

Thank you for the wiring diagram.
Jayco sent me the same drawing number that showed the relay locations but did not have the wining diagram.
Found a frayed wire loom last week end and now I know it is the generator auto start harness.
Time for a new fuse block and clean up the sloppy wiring.

Just finished up with a hitch upgrade. Installed a Reese/Draw-tite Super Titan 3 inch Receiver Hitch. Even though the factory hitch was rated at 12k and I usually pull at about 11,500 with the trailer fully loaded I didn’t like being that close to the maximum. I also like that it has dual stacked receivers as my trailers ball heights vary and I can use just one straight ball mount. I did have to trim the rear bumper/cap but it wasn’t that big of deal for me and this hitch sets flush with the bumper and sits higher than the factory one for better clearance.

Made some room in my wet bay. I can get to my water now if I need to.

Sorry!

Get to my water pump when I need to and see the Dr. Seuss piping behind the panel.

Moved my main slide relay and bedroom slide controller so I can access them without tearing the bed apart if the slide won’t go out.

Did you simply cut the panel while still mounted to the RV and then add the bracket?

Interesting, I did the same thing.

While testing the process for manual slide push in/out it became obvious I could not get to the slide controller.

I wonder if the manufacturers of these RV's actually test failure modes!

The bed covers up the controller whose access is needed to manually move the bed!

See some videos of what I did here: https://donstronicthings.blogspot.co...r-remount.html

I did my cutout in place with a utility knife. I added plywood behind it for mounting.

Installed two usb charging ports on the dash and moved window and engine brake switch to make it suitable to me.

I got the console.luv it! But a year later and it’s rusting!

[Bruceter]

Finally have one compartment finished up the way I wanted it. Next in the list is the utilities compartment

What slide-out tray did you use? Thanks!

[Bruceter]

I had the aluminum tray built and used slides from Lee Valley Tools.

Took the sag out of my plastic storage box with some unistrut channel.

[Rustynuts]

For the saggy compartments I have been bolting on aluminum angle with a fender washer on the inside. Straightens them right out and makes them rigid.

With my wife being an early riser, I finally added a outlet in the kitchen for her coffee maker so she won’t wake me up with the generator I just ran a line from the Microwave plug over to the next cabinet and cut a hole for it. Pretty easy project if you just pop the staples on the inside cabinet bottom, only half of them actually we stapled into anything. I use a small #6 bronze screw to fasten the panel back down. Don’t know why I waited so long, only took about a half our to do.

We had bought a 2020 Thor Tiburon, and loved it, but after driving across country (Florida to Seattle) really discovered that it was a bit too small (and wiggly from wind) for long time travel – SO – we traded up to a 2021 Jayco Seneca 37K – and LOVE the layout, all the new space and the safer feeling while driving. We live in Florida, and found it in Texas – so a 3 day drive to go get her…

The Ugly on delivery:

The outside radio did not work. They sent us a new one, but it turns out that it was wired to the ignition, and not the batteries, so would only worked if the engine was on. Husband fixed that and now it all works!

House power battery disconnect light switch (by entry step) did not work. Husband took it apart, and found that the wire was not connected.

Combo washer/dryer was leaking when it drained. Had to take that one in locally to get it fixed, as guys in Texas couldn’t find the problem soon enough before we left to drive back home. Just fixed today!!

Backup camera was installed wrong, so it only looked straight down to see bumper. WHAT! Husband had to get up there to turn it around to fix it.

Could not get any cable television when it was all connected up – so after following the wires –discovered that the cable wire was connected to the Satellite Connection! This was found in the control panel that was located BEHIND the fireplace. Switched it over to connect to cable – and all worked!

Refrigerator door was dented on pick up. It swings too wide, and someone let it swing into the fireplace corner – and bam! – dent! Dealer is sending us a new door – which we are still waiting for.

Oil leak – took rig to Freightliner to fix, and they did.

All in all – not TOO bad. We have learned that you really need to be a well rounded fix-it person in order to own a rig – as from the get go – there were lots of little things to fix and wires to tie up. Very luckily, may husband is!

Made a much need cargo mat for the front cab. Found some fabulous rubber fabric at Sailrite.com, as well as pattern making material. Watched an instructional video (though it was for a boat mat) on how to make one. (Love this website.) Gave it a shot, and LOVE how it turned out! I used this fabric in case anyone else wants to give it a try https://www.sailrite.com/Chilewich-I...overing-Fabric but many to choose from. (This one happens to match our walls very well.)

We also bought the much needed center console (and scangage) from https://www.build5fab.com/Jayco-Seneca-Console.html As a note – I have NO problem walking to the back with this console installed. IT IS HEAVY – made out of steel – so should last longer than the rig! My husband also installed 2 more USB outlets in the top of it. YAY!

NEXT – we HAD to replace that Sony radio! We didn’t like the fact that we had to get directions using our phones (what if there was no cell coverage??) – so we chose the Kenwood DNR1007XR that has Garmin Navigation – and love it! This, we had installed professionally.

Since we have a BIG dog, my husband made as step cover so he would have more space when we travelled. Perfect! Also, notice on the door that we added an additional handle. This makes closing the door SO MUCH easier and easier to reach as well! That we bought on Amazon: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Next, we lined the pantry shelves with left over floor mat material, and added motion sensor lights to the top lip of the underside of each shelf. Makes seeing in there SO MUCH easier! We used these lights:
