Can someone please guide me to find the right fuse inside the fuse box for the factory’s fog lamps. I’ve read manual and can’t seem to find it or at least the correct naming for it.

XLT replaced factory bumper for OEM Raptor, adding RIGID (scenes) pods, did all of the wiring myself to connect to factory fog lamps, 3 pods per side. Supposedly, each pod runs about 2A, I need to know what’s the amp total on that fuse IF there’s even one.

THANKS FOR THE HELP!

 

The year & model may give us a clue..
.

 

It’s a 2018 XLT model.

I’ve read somewhere the Raptor has a 15A fuse, and the pods I bought pull about 2A each (x6). Just need to find the fuse on my XLT and make sure it’s rated the same as the Raptor fuse.

Thanks for the help!

Fog lamps are only indirectly protected by the fuses that provide power to the BCM. Fog lamps are powered directly by the BCM and protected from overloading by FET (Field Effect Transistor) circuits built into the BCM. One FET circuit for the left hand and one FET circuit for the right hand. In the event of drawing too much amperage, the FET will trip shutting off the circuit and preventing further overload. The FET will automatically reset on an ignition Off-On cycle. If the FET trips too many times, it will set a DTC and not reset until the DTC is cleared.

The only way to find out if you are good to go is to try it. If the lights trip off on their own, you know they are pulling too much amperage. Then you would need to use a relay to power the new fog lamps. Use the factory fog lamp circuit on the relay solenoid to actuate it and get power for the lights from the battery protected by an inline fuse.

 

Thanks, brother. But it’s the same info I find everywhere, only thing I see related to lighting, trailer tow lamps and spot lamps. Nothing says headlight nor fog lamps.

 

Thanks, man. That makes sense. Lamps are ready to install, just need to do some trimming and will see how it goes!

 

The same is true for all the other lamps in your truck, not just the fog lamps.

 

I just did a quick test. I plugged in the fog lamps, they worked. They do not work when the key is in the ON position, has to be running for the lamps to work. Not that I can remember if my OEM fog lights worked when the key was in the ON pos before. **face palm**

 

On both my trucks, engine has had to be running to turn on fog lamps.
