OEM fog light wiring and diagram

I have the lights and I have the switch with the pigtail connected to it. I am guessing I need the intermediate wiring that goes fom the pigtail to the connections on the light. I would like to hook them up the same way as OEM.

Does anyone have the wiring diagram for the fog lights? I looked in the FSM but doesn't seem to explain it. Or, can anyone explain the connections? I have gathered from searching that the f/l switch ties into the low-beam wire of the light switch.

Thanks in advance.

Hook them up like this. Fog Light Wiring with Bosch Relay

Connecting to the low beams is not needed unless your state laws require it.

Thanks for the link. That's how I plan to do it if I can't figure out the way the factory did it.

As defined by FEDERAL DOT LAW,
And adopted by most state laws,

Your 'Fog' lights must NOT operate when high beams are on,
Must be AMBER,
And must be directed at the ground directly in front of the vehicle.

You can wire them to automatically disconnect when you hit the high beams,
And you can have them on when no headlights are turned on.
----------------------

Now, if you are talking about driving lights,
Again, the law is VERY specific,
One pair of PRIMARY driving lights (LOW BEAMS), White in color.
One pair of SECONDARY lights (HIGH BEAMS), White in color.
One Pair of 'Special Purpose' lights, Amber in color (FOG LIGHTS) are allowed.
There are also specific distances from the ground that forward facing lights can be...
Minimum and Maximum, and I can tell you, they don't allow roll bar mounted lights!
Most under bumper lights are too low and 'Illegal'...
Even though it's not enforced most places, if you travel, sooner or later you WILL find someplace that will fine you!

Like Las Vegas crammed three tickets up our butts two years ago for having forward facing white lights other than 'Primary & Secondary (high and low beams),
'Rock Lights' in the wheel wells,
And rear facing lights on the roll bar...
And it was at a 4 wheel drive show on the road in front of our hotel!

The laws are enforced VERY spotty though,
Some places let you get away with forward facing White lights, like driving or off road lights,
Other places require you cover them up when on the highway.
Just turning them off isn't enough...
(ask me how much it cost me to learn that in California... )

Let me know what lights you plan to run, and how you want them to work, and I can likely throw you a wiring diagram that will fit your application...

Thanks for the informative reply, Jeephammer. I have a pair of OEM Marchal lights and an OEM switch with the pig tail. I prefer to hook them up OEM if possible.

Meanwhile here in NY I had 8 Hella 550's in driving pattern plus another 4 500's in amber fog hanging off the bumper of my old J20. 100w all around too. The only comment I ever got from The Man was why were they point this way and that and I had to explain; ditch light, crest light, ascent light and long range highway. When the array was on and filled in by the 100/140 H4 mains it was a sight to behold.

OEM Maschal fox heads do look very period pimp but I was never too happy about their anemic beam pattern, like glorified position lamps. Hella and Cibie always had them beat on performance.

OEM Jeep SE Marchals'

Once you have the green rocker switch and the harness with relay, you will see where it plugs in near the headlight switch.

This whole underdash wiring harness with relay is about a foot long.
Green rocker switch is mounted underneath speaker underdash on a little right angle bracket.

There is a red or orange wire in headlight harness with a white connector.
There is a light wiring harness which is about 3' long that goes to each light and to this orange/red wire with connector. U will need this also.

Don't have to fish or run wires thru the firewall, the wiring is already in all 82-86 CJ's.

Sorry I don't have any pictures.
But if U got the 2 wiring harnesses it's super easy and no way can mess up.

Thanks for the description, Red. I have the switch with relay and if i understand correctly:

1) there is red or orange wire in headlight harness with a white connector that all 82-86 Cjs have and it runs to the headlights.

2) From this white connector there is a 3' light wiring harness that goes to each light. I don't have this 3' harness but I imagine I can fab something up. The lights have the original connectors and I would rather not butcher them. Anyone know off-hand where I can find these? I will try a search in the meantime.

Cowboy - you're right they are not very bright and wouldn't be my first choice for illuminating anything. You must have had one bright J20. I had 4 old 6" KCs at one point and that was pretty bright.

Thanks again.

I think a place like Ron Francis wiring will have the OEM connectors you need and you can make your own harness.

You can try collins brothers as well. They keep a lot of old wiring crap laying around. I just got a pigtail for a running light

They don't have to be amber. My 95 BMW convertible has factory fog lights, and they are white. Just take a look around at all the newer cars with fog lights, and most (if not all) are white, not amber.

My F150 are also white and not amber. The rest applies though, they can be on by themselves or with the headlamps but always shut off with the high beams on.

I have an original rocker switch for Jeep fog lights.

Thought I would ask if anyone knows the wire codes.

The switch has four pins

The harness has three wires
red with white strip heave gauge, may be a 12 gauge (feed wire????)
Gray with a black strip light gauge (14 or 16 ground?)
blue or purple may be 12 , could be 14 (switched hot?)

If no one knows I will go play with it in the basement and let you know.

Ok, this is what I found and it may not be correct for the original Jeep wiring.

My intention would be to use this switch to complete the circuit of the rely for my driving lights.

Jeep may have used it for the ground leg of the relay for the fog lights.

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

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.
