Fog lights on factory wiring
Hey all,
My jeep had fog lights from the factory which i would like to replace/upgrade with either fogs or driving lights.
Can i simply add some driving lights and splice the into the factory wiring?
Also how do i test the factory wiring to see if its still good, i dont have any fog lights currently on the vehicle. i have a multi meter but i dont really know what im looking for.
thank you for any assistance

If you go with LED lights, NP low amperage draw. Otherwise you will need to know the amp draw of the new lights, you will want the same amp draw as the stock lights or less. I don't know what amperage the fog light circuit is, sorry.
Testing. Your fog lights were plugged into wires with plugs on the ends which terminate right behind your bumper down by the fog light mounting areas. You need to locate these plugs, turn on the fog light switch and your volt meter (DC). Now, while holding the black volt meter lead to any bare bolt (ground) touch the red lead to one and then the other hole in the plug, you need to make contact with the metal in the plug holes. You should get a reading of about 12 volts from one of them, if not, check the fuse for the fog light circuit and repeat the voltage reading steps. Good luck.

If the lights you choose are a high amp draw, then I would suggest you use the existing wiring as a control circuit. Wire a relay to the end of the existing wire (behind the bumper), then run a new harness to the lights from the relay. Much easier than running new wire into the cab to a new switch.

I have the fog light wiring harness from a 1989 xj on my 1995 xj there is a relay where the fog light wiring joins main wiring harness iam running 2 55 watt fog lights without a problem. If you want higher wattage fog lights you may need to put heaver gauge wire from the battery to the relay and then from the relay to the fog lights.

Should be around 10 amps for both 55w lights at 12v. Used several sets of cheapo leds from amazon and so far ive only had one bad pair. Ive got 4 of the rectangle floods for rocklights and they've survived for about a year now.

i have been running LED fog lights for 2 years on my cherokee with no issues. i took the stock fog lights cut the ends off and wired the ends on my lights so i didnt need to cut the factory wiring. i havent seen any issues.. only thing is my light inside the cab doesnt fully light up i believe due to not drawing enough from the lights.

snow/fogs
Ive been researching lights more now and led are great but i dont know how much we loose out on beam pattern vs hid or halogen.
i would like your help for those that run fogs or such in snow. Do hid vs halogen melt snow well vs led which are cooler.
yellow light is optimal for me, what have others here found for their driving needs?

Honestly unless you got 300 bucks to spend on hids i would pass on them.A fog light goes under the bumper and does help in fog/dusty and light snow.Yellow light does help in snow.More light then that driving lights on top the bumper can help and depending the brand you can get yellow light covers for them.

Power goes from the battery to the fog lamp switch through that relay, then from the switch straight to the fog lamps. In other words, all the current for the fog lamps goes through the fog lamp switch.
Just like that infernal headlight switch.

Hey Wizard. The pic is of the wiring diagram in my service manual. It clearly shows the fog lamps being powered through the fog lamp relay. The fog lamp relay is energized by the fog light switch which receives its power through the headlamp dimmer switch. So, the fog lamps are powered from the battery through the high amp fog lamp relay.
