Mine are on with the key. I'm also going to have them go on with the dome light, as soon as I have a diode. They aren't too bright, and I think they look good, so I just always have them on. I have a switched fuse box that I used.

Since I'm using carling contours v three ways, the two LEDs each have to be grounded separately. So I made this little negative ground harness, daisy chained together. Four switches times two LEDs per switch equals 8 connections.

I wanted the green lights to be on with the ignition, so I daisy chained the four spades for those. I have them wired into both my switched fuse box, and also to the dome light (using a diode) so when I open the door at night, regardless if the ignition is on or not, the green wording lights up so I know which switch is which.

Green on left side. Not too bright and kind of matches dash.

Side note, I use a $160 crimping tool that gives me factory like crimps. With the jeep bouncing around, these crimps are vital. I also use adhesive lined heat shrink which glues the connection together. The combo of good crimps and this heat shrink results in a connection that cannot be pulled apart. When I wire for others, I guarantee my wiring for 10 years (no kidding).
<img src="https://www.jk-forum.com/forums/attachment.php?attachmentid=421196"/>
So on my switches, they're on-off-on switches. With these switches, I can have the switch in "auto" mode and have my reverse lights go on when I go into reverse. If the switch is in the middle (off), the lights are off. And flipping it the other way (in my case to constant power) the lights turn on manually. Well, there are two LEDs on the switch, and I wanted the orange sides of the switches (the logo side) to go on regardless of which direction the switch was switched. When I switch I to reverse, the orange lights goes on; when I manually switch it, the orange light goes on. In order to accomplish this, you have to jump the positive to the orange led to the center output spade on the switch. Hence these double jumpers.

Here's what it looks like hooked up. By the way, I used 18-4 black jacketed speaker wire for my setup. There are four wires with different colored wires in the same sheath. I cut all four about an inch apart so they lined up better when plugging them in. Remember I'm going to have four inputs in "auto" mode, four inputs in constant mode, and four outputs; a total of 28 spades on these four switches. Being organized when cutting and matching colors up saves a lot of time. Wire management is key, because it gets really tight on the back of the switches.
<img src="https://www.jk-forum.com/forums/attachment.php?attachmentid=421204"/>
Next was my first "harness" as I'll call it, for the auto side of the switch. Again, I cut the four wires to the same spacing as the switches, and used the same color coding on the input wires as the output wires (for me it was red for top switch, then black, then green, then white, from top to bottom). I made two of these (one for auto side and one for constant side).

Another side note: I've been wiring for almost 25 years (I'm 40 years old). This is my connector box. Having all of the proper ring terminals, spade terminals, Molex connectors, crimp tools, heat shrink, heat gun, wire stripper (another $140 tool) makes all of this easier. My garage is like a factory and it still took me 10 hours!)

One harness, with heat shrink on every connector.

The reason I'm calling these harnesses is because I'm putting disconnects at the bottom of all three of them so that if I have to get the jeep serviced the dealer can unplug these without cutting anything (not having to unplug anything at the switches themselves). The plugs will go down in the dash side compartment cover. So I marked each harness near the top and near the bottom, so once I put the pod in, I don't have to remember which harness is which and what color wire controls which switch.

Since this harness isn't exposed to moisture, I added just a dab of dielectric grease to make sliding them on easier and prevent any corrosion. Not necessary likely, but it can't hurt.

28 connections. Three main harnesses: output, auto Input, constant input. Then I had two loose wires: black was ground for everything, and red was the positive for the green LEDs.

Tested everything on my spare battery before putting in. Everything was in order. Orange light on regardless of which direction I pushed the switch.

Here's the bottom end of each harness hanging down out the side port at the end of the dash. A perfect place to hide everything and easily access all wiring. Notice how I cut the harnesses a little different length so all connectors didn't bunch up at the exact same place.
<img src="https://www.jk-forum.com/forums/attachment.php?attachmentid=421224"/>
I realized that I didn't have any Molex 4-pin connectors, so in the short run, I added Posi-Locks to the end of each wire. These are toolless connectors that can be reused and will keep any unused wire from shorting out. Once my Molex connectors come in, I'll add them to the end of all wires and I will truly have pigtail harnesses that the dealer can unplug to service the dash.

Once all that was done, It was then just a matter of getting input and out put wires to the bottom of my harnesses. I was using the black 18-4 wiring which was nice, and I ran it through the hole to the top left in the pic (my dash hole down below is just about maxed out).

I have two blu seas on a custom sPOD mount I did; one is constant, one is hot. Here's a summary of my inputs per switch:
Reverse switch: constant input from constant fuse box; auto input tapped under passenger footwell. White wire with thin gray stripe. Causes Dually D2s in my bumper to come on with reverse lights. For those, I'm using the relay that came with them Mounted next to my battery. The relay lead is what goes to my output wire on the switch. To get the wiring back to the lights, I actually fished the wire through the frame of the jeep (yes, inside the actual frame); I figured it would never get hung up on anything while wheeling,
Driving lights switch: same as reverse basically. Constant feed from constant fuse box. Auto feed from a wire I tapped I to the high beams up by the bulbs and just ran the wire back. Output goes to the relay that came with the D2 Drivings on front bumper.
Fog lights: these are PIAA LEDs and I'm using them as DRLs. So one lead is from the switched fuse box and one lead is from the constant fuse box.
By the way, I'm using the constant fuse box on the one side so that I can reach in the jeep at any time and turn some lights on. I load a trailer frequently and have the reverse lights on their own switch where I don't have to turn the jeep on will be nice. Remember, my green led illuminating the switch name turns on with the dome lights when I open the door, so voila, I can see what is what when I open the door.
My last switch says dome lights, but I'm actually putting Rigid SRM red diffused on the taillights. They will be wired as constant (for fog and heavy rain) and I'm adding a strobe flasher for emergencies and pulling over on the side of the road. Same switch setup, but the wiring is a little backwards on that once since the flasher is in the mix. For this switch, there's one constant input and two outputs, so the switch is wired the opposite of the others (which have two inputs and one output). Pm me for more info.
By the time I got everything wired, it took aBout 10 hours. It looks almost oem though! Okay, my fingers are sore, I need a break,

Great write up - wish I had a fraction of your electrical skills!
Two questions. First question is a general one - what gauge wire should you use when running wires for lights in a Jeep? I usually use what they give me but I want to clean it up and do the install from scratch. Second is about how much work was needed to get the switches to fit in the RR A pillar mount? The switches you have are perfect (I couldn't find too many switched that were horizontal) but im concerned on how much sanding is needed to make them fit.
Thanks in advance!

With regard to your second question, it took me longer to correctly seat the RR A pillar mount than it did to actually wire the switches. Using some of the guidance from the OP, I created a common grounding harness and two of my switches had a common power harness. And I even managed to wire the correct terminals on the first try (go figure!). I grounded all switches to the pot metal thats just behind that side panel you removed to get access to this area; just drilled a hole and used a sheet metal screw to secure the ground wire terminal.
With regard to sanding, it's probably no more than a 1/16" on each switch. I used an abrasive disk on my table saw and it took no more than 20 seconds for each switch (I didn't have to take the rocker off the switch). i dipped a Q-tip into some black Rustoleum paint to cover the sanded area, let them dry, popped them into the pillar and they fit just fine.
Again, the hardest (and most disappointing) part was getting the RR A pillar to sit flush with the long edges. The plastic doesn't have quite the right shape to fit like the OEM part.

Asking about what wire size is kind of like asking someone, "what tires should I buy?" The answer: it depends. Although it is pretty black and white based upon load. Here's a thread that explains wire gauges from me:
https://www.jk-forum.com/forums/jk-e...itique-262954/
Call me if you want me to talk you through it. I'm too tired to type. 314-680-2624. Due to the space limitations of the JK, my best advice is to go as small as is safe for the load. 18 gauge is more than plenty for wiring relays; 22 is actually fine, but it's so small it's hard to work with. I started with 18-4 speaker wire and it worked great (18 gauge, 4 conductors, separately colored, in the same sheath).
