my warranty is long gone i dont careDepends, are concerned about any warranty issues? I assume not sure to the age of the vehicle. But I would either start with a conversation with your local dealer or try something like this:

Hmm. no diagram but a couple of photos with explanations.Eh Oldfooladventures Moak, you would have a wiring diagram for that KISS method would you? I like quality and impleness, I am also visual :)
I got a 1978 dodge with a 360 and want duals. one day I'll get a 200+ battery but for now I'll run the 125 - 150s they at least start the engine great.
I've had the National Luna system installed for over two years now and have had zero issues. I will say that it is important to view all these systems as a start point. It's critical to properly set them up with isolated in-line fuses and manual breakers. Doing so ensures you can isolate the controller whenever the vehicle is stored and if the solenoid does ever short it will immediately trip a fuse and not drain a battery... or worse. Investing in the right gauge wiring for the span is another essential safety step.
Nice clean setup and similar to my setup. I invested in an SPOD, so the Auxiliary battery goes to it, then out to the accessories. It has a nice switch panel that is above the mirror, so its out of the way. The complete installed was engineered from wire sizes to loads on the battery and alternator. I have inline fuses from everything that leaves there battery. The issue I had with the National Luna setup was the solenoid was bad and would drain the battery in a night. I found it when I burned myself on the solenoid while troubleshooting the issue. Easily fixed and haven't had an issue with it since.
I have a second accessory system off of the main battery. These are mostly lights and run while the vehicle is running. Like your system, it runs to a circuit breaker, onto the fuse box, and then switched inside the cab. Great pictures!
I installed a National Luna System and it is not reliable, the cable that attaches to the spiraling light display, which shows your degree of charge, comes loose. Overland Journal, summer issue, rated many dual battery system controllers and noted the same weakness. Editor's Choice was the Intelligent Battery SystemI have a 2011 Jeep JKUL Rubicon and I installed a National Luna Dual Battery System Kit, with surface Mounted controller. I can say that the installation was a like putting frozen Jell-O in a balloon. You can do it, but you'll only try it once. First the 2011 Jeep JK has minimal extra space in the engine compartment. I found a bracket that bolts in place, but if I ever need to change a manifold, it's got to come out. I can't remember the make of the bracket, sorry. I changed the batteries to AGM Batteries. I have one Red Top (the main vehicle battery), and one Yellow Top (2nd battery for accessories, deep discharge). They fit like a glove!

The National Luna Intelligent Split Charging Kit is a complete turnkey Dual Battery system, that includes an Intelligent Solenoid, Dual Battery Controller, and all the necessary materials to complete the job. Across the top of the batteries, I had to manufacture a bracket to hold down the controller and solenoid that separates the batteries. The remote surface mounted controller had a long cable and is mounted inside the center console (I swapped out the OEM console for a Tuffy security console that has this little shelf, almost as if it were made for the controller). A near perfect setup!

Now the bad news. The first issue I had, was when I had to travel overseas for several months. The controller or solenoid has a trickle discharge I didn't know about and both batteries were dead by the time I came home. Fortunately, the guys (and gals) at Optima told me how I could try (and did) recharge the batteries. The second more troubling issue was when the solenoid shorted out. The batteries were severely discharging overnight. I thought it was because of the first issue until I touched the solenoid and burned myself. Needed a new solenoid, which National Luna gladly sold me.

The system works, and when it works, well. I wouldn't recommend it as a first choice and now that these are more common place, I'd have to do more research on what is out there. But I can't argue enough for a second battery system. I run my radios (a must to reduce noise), some auxiliary LED lights, and refrigerator off of the second battery. The main battery has the winch (a must), the off-road lights, and vehicle systems. The alternator keeps the batteries charged, but I'd still (and am currently) considering upgrading the alternator.
