What are these wires for?

My 99 tj 2.5 has 3 "dummy" switches on the dash, on other units Ive seen the switches run the fog lights (i dont have) rear defroster (i dont have) and on the rubicon the lockers (you guessed it, I dont have)
What I do have is the cover plates to fill the holes...BUT on the back side is a small loom of wires that stops at where the switches would be it has 1 plug with 4 wires the colors are: green/yellow; Brown/white; Orange; Black.
Any idea what they power up?
Thanks

I must be missing something

From what you said, I'm guessing that they power nothing. They run from where the switch "would be", to where the component "would be" for the 3 accessories you don't have.
Good thing is, you can easily upgrade if you find a Rubicon in the yard that has those accessories.

You will find that when the make most vehicles, there is no difference in wiring harness regardless of actual options. It's cheaper overall to have one harness that has everything.

So...that means that you already have most of the wiring you need. You will most likely find a wire up around the front that is not connected....it is most likely the fog light. And somewhere in the rear harness you will find another wire that can be used for the rear defroster. And somewhere underneath will be another that can be used for lockers......

Like the commercial.."it's all there"....

Well I understand what you are saying, I have found that in other autos that I have owned. My question more spicificly is, would the single plug outlet that I have power the fogs, defroster, or (I doubt lockers...didnt the Rubicon come out in 2000?) thanks

I don't have that exact answer....for that you really need the FSM (Factory Service Manual).....which you should really have anyway.

That's for the rear bumper mounted fog light on export vehicles. You could get the switch and relay if you have the rest of the wiring and use it for a rear mounted spotlight. The circuit can be switched on or off with a single press of the switch and if you turn your headlights off it resets to to off state so it won't get left on.

i don't know if the 03 of the wifes is the same harness, but the fog light switch is on the turn signal arm!!!!!!!

Stop and look at it!!!!!!!

Tim

Why is it that after you get stuck everyone helps you out then tries to make it though the same spot???

I was aware the fog switch moved in later models but the OP has a 99 and so should be very similar to my 97. I checked the wiring colours in the FSM and it doesn't show on the diagrams for US market vehicles only for LHD and RHD export models.
