Red with the white strip is the ground
Blue is the switched hot
Gray with the black strip is the hot feed.
I would have guessed red is the hot feed,
blue the switched output,
and gray the ground for the light.

With it wired this way the indicator light comes on when the test light (driving lights (which are run with a rely (switch not carrying the load for the driving lights))) come on



and goes off when the test light is off.


Did you know the plug may already be behind your dash. They left them there so they only would have to make a few harnesses so accessories that were not used were not plugged in but the wiring is still in place.

Here is what the schematic shows, the light is not to indicate the Driving Lights are ON but to find the switch in the dark when the headlights are on. Or maybe when they can be turned on. I Know I Know, it seems backwards but that is what the schematic shows.

The only time the light on the switch is activated is when the LOW beams are on. When you go to High beams, they turn off.
There always is a possibility that the switch is wired different and goes off and on


Power for the switch comes from the dimmer switch on the GREY wire.
The RED/Trace wire goes to ground AND one side of the relay coil. I know odd but it actually splices into a black wire to ground.
The Dark Blue wire is switched and goes to the Relays other coil connection.


Power for the driving lights come from the Parking/tail light fuse.

It took me a few minutes to cypher through that schematic, but that is indeed exactly what it indicates.

interesting.

That sounds like the way I test wired it, but the indicator light went out when there was no power to the test light.

You suggest that when ever there is power applied to the gary wire (from the dimmer switch or in my case the power supply for my relay) the indicator light should be on regardless of weather the switch is turned on or not.

I will go back and check my test set up, because the wiring diagram says you are right.

Based on the diagram if I used the blue as the supply and the gray as the feed the indicator light would go off when the switch was off and would be on when the switch was on and would supply power to the driving light relay.

Yes, it would work that way also.

Got a picture of the back of the plug?

Notes
1) That the red wire with strip has been poked
2) The single rape of tape around the wires looks original.
3) The plug can only be plugged into the switch one way

My only thought is someone played with it and decided to make it work "correctly", and swapped the wires around in the plug.

I'm about to take the wires out of the plug and crimp in new ones .

I did set the test up again and it works as previously stated. Switch light on when power supplied on switched leg, switch light off when no power supplied to switched leg.

So when you push on the green dot, the light comes on
when you push on the fog light drawing the lights go out...

Hmmmm...


I wish I knew what terminals the light is hooked up to/ Can you probe around directly on the switch and see if you can make the light come on regardless what position the switch is in?

Is that a bulb or LED?

Please do, We need some more pictures of an OEM switch and connections.

Hate to base all my conclusions off one switch.

It is a filament bulb

I will do, but I will have to do it from the switch pins as the old wires have been removed from the plug. I was just about to plug it up to my wiring harness I made for the driving lights.

The first thing I will try will be to reverse the old gray and blue wires, I suspect that will give us a light in the switch when ever power is on the blue and the light will remain on when the switch is in either on or off positions. Lunch first then experiments.

I agree the same, the red with white strip is on the side by itself.

Mine

Ok,
I taped to the switch pieces of the original wire in the location they would have been connected to the switch.

with the
Red with the white strip as the ground
Blue as the switched hot
Gray with the black strip as the hot feed.

The light in the switch goes off and on with the switched leg on the switch

with
Red with the white strip as the ground
Blue as as the hot feed
Gray with the black strip as the switched hot.

The light in the switch stays on when every there is power applied to the blue terminal regardless of what position the switch is in (on or off). The test light only comes on when the switch is in the on position.

This is the reverse of the way the wiring diagram says it should work.

Ok, the switch is in the Jeep.

and it functions the way I wanted it to (indicator light on when the driving lights are on and the indicator is off when the driving lights are off.

Interesting note is after all the testing to find out how to hook it up so that it would work this way, didn't I hook it up so that the indicator light was on all the time!!!!!!

I covered the headlights up so that if you look at the wall infront of the Jeep you can tell if the lights are on.

Well this is the reverse of the schematic but the way the the schematic said it should operate. Seems like the engineer said it should work this way and some tech said Naw, you want it the other way..

I use to hook my lights switches up so the light was on when the fog lights were on. But then I had to hunt for the switch in the dark.
Since then, I hook switch light up to always be lit and used another light to indicate when they were on.

Oh well, at least you got it to work the way you want it to work.

My thoughts are I will have to prethink turning the driving lights on as I have to remove the covers. I will not be trying to turn them on while driving in the dark so do not need the light to locate them.

The other thing I noticed is in this picture



The fog light emblem is facing horizontal and on my switch it is facing vertical



So.... maybe mine is not original but an aftermarket look alike or there were different versions???????
