so i just installed my new bumper and valence with fog lights today, but i didnt have them before. i plan on putting hids in them and was wondering how they would need to be wired up. can they be wired into the headlights so when the headlight switch is on they come on?

 

i would go to the junkyard and get a bezel from a truck originally equipped with foglights and cut off the harness plug for the switch. wire the foglights to that switch using the proper sized fuses and activate the circuit with a relay.

i dont want to have a switch though, i just want the fog lights on with my head lights

 

Set up the fog light switch/relay to come on when you fire up the truck.
This way you will have the fogs on all the time, sort of a daytime running light.
Find a wire that has power after the engine is started.
Run a fused wire from that point to pin 86 on a relay and ground pin 85; now when you turn on the truck the relay will click, if not check out the wiring.
Then run a fused wire from the positive battery terminal to pin 30 on the relay and from pin 87 run another wire to the lights.
Size the wire and fuses according to the current (amps) draw for each section, i.e relay draw minimum current so a 1 or 2 amps fuse will do, the HIDs will draw less than OEM Fogs but check out the manufacturers amperage figures and size everything on that section of the circuit 20% heavier than you need.

I hope that isn’t too confusing.

When running the Fogs off the headlights circuit you will need either a double relay setup or run the lights on either low or high beams.

Good Project, good luck.

 

you can wire them up this way^^^ or use the marker lights to turn on your relay instead of the headlights. this way the fogs will stay on with high and low beams.

 

well i dont use high beams anyways so it wouldnt make a deffernce to me

 

Same thing, find a power source, i.e. parking light… good idea they will be on with the parkers or the headlights, nice.

This is easy to do, when you get there let me know or check out some of the How-To’s on the site.

 

could somebody draw me up a diagram, im not wiring savvy

 

Here is a how-to

Check out the schematic in the thread.
Instead of a switch to activate the relay use the parking light wire on pin 85 of the relay. (85 and 86 are interchangeable)

Hope this helps.

 

im not a very good electrician but ill give it a shot

 

Ok on the wiring, just ask questions.

The hardest part will be finding the parking light wire in the harness.
Use a 12 volt probe, turn on the parking lights and start checking wires for power.
Might help if you look on the parking light socket to see what color wire is there.
There should be at least two wires, one for the parking lights and one for the directionals, maybe a third for a ground. Then find the same color wire further back in the harness, closer to the firewall, check the wire for power and tap the wire.

Take your time.

 

check your local (state) fog light laws. most allow them at any time, but a few states will ticket you if your fog lights are used in clear, non inclement weather situations. and to make matters worse, if you cannot turn off your fog lights if a cop tells you to do so, you just might get your truck towed.

 

Good point !

Easy to add an additional switch.
There are two ways to approach the switch wiring so post up what you will be doing.
