So I have a non Rubicon Jeep (2003 model) and I'm installing axles that have arb lockers in them. I would like to wire up the switches to the instrument cluster lights that light up the "front locker" and "rear locker" beside the 4WD light. Does my instrument cluster (non rubicon) have those cut outs for lights & the lettering? Has anyone done this? I like to look of stock stuff and having the lights right in my face will remind me its on...
Instrument cluster locker light question

I believe all Jeeps of the same year have all of the lights, just that hey aren’t used in most of them. This also applies to the shift light, the cruise control light, etc.
You’d have to read up on the function in the FSM to determine if the instrument cluster locker lights can be turned on or not. I seem to recall the instrument cluster actually having a role in turning the locker pumps on, but I could be confusing it with the PCM. The instrument cluster definitely controls other things, such as the heated back light timer.

Somewhere, out there is a mod to use the factory locker lights with aftermarket lockers. It involves 2 regular diodes per locker and some wiring.
Ok looking at the bottom picture, few questions:
Do you need 4 diodes for wires 6, 7, 10, 16? Or can you use one diode for 6 and one or 10 (hot wires)?
I just wired it up and the lights are on and flickering constantly even if I disconnect the ground. When i remove the keys the lights still stay on. I’ m assuming i put the Diodes in the wrong way?
time the break out the soldering iron again
It is easy to tell if the lockers are on by the behavior or the Jeep. Going perfectly straight is the only time you can't tell if they are on. Mine doesn't turn very well with the rear locked and even worse with both locked. When the front is locked the power steering make some noise. I think you will find that the lights only confirm what you are thinking by the behavior of the Jeep. You can always use switches that light up when turned on.

Yes, 4 diodes total. Two per locker.
Mind you, this is not my mod. I have not yet done this. But, what I understand is that the locker light blinks (front or rear) if it doesn't receive a ground signal from two locations. That's why the two diodes for each locker.
My lights dont come on at all. 06 Rubicon. 4wd, F lock, R lock. What causes that? Those diode things?
No slow blink?
Are you sure you're locked?
Maybe the bulbs are burnt out or removed (for some odd reason).
I know this thread is 4-5 years old and I’m not sure you’re still following this forum, but I’m in the middle of this swap and had a question on the above diagram. When this is wired for the locker engaged lights in the dash, will they blink when the lockers trying to engage and then go solid once they’ve engaged? I’m trying to figure out how the light is getting current when it is blinking and when it is solid because based off your diagram, it looks like it’s just a ground wire that closes the circuit once the locker engages.if you have any feedback, I’d appreciate it thank you.
The diagram above is for non-factory wiring, specifically for the dash lights to function with aftermarket lockers.
I have an 04 Rubicon so can describe how it works. The diagram is to light these indicators in the dash for a non-rubicon model.
When you select one of the lockers, the light blinks when the air pump is on. Inside the rubicon diff there is a switch that is pushed out when the locker air bladder expands all the way closing the circuit. When this happens the light goes solid.

That will not work like the factory lights.
The factory setup uses logic in the instrument cluster to blink the lights by comparing the switch request state to the locker state. Mismatch equals blinking. Matching equals solid light engaged or no light for disengaged.
