So to sum it up I have a 2007 ford f150 I just installed LED headlights when my fog lights are off they work with no issues I have a low and high. When I turn on my fog lights my high beams turn on and the high beam indicator shows up dim then when I turn on my high beams the indicator lights up to a solid blue but the fog lights do not turn off. I know this issue is directly related to the LED bulbs because I took my truck to a shop a year or two ago and had them install an HID kit and it worked fine but both headlights were also grounded to the frame and the headlights had a ballast that was directly connected to the trucks positive side of the battery. I signed up because I need help to resolve this and I was digging around google and this forum one post said to go to this site which is no longer in service and said I need to isolate the ground for the fog lights to fix the issue. But then another person posted that it still did not resolve the issue just made the Fog lights work correctly.

The topic I am talking about is located here https://www.f150online.com/forums/el...-confused.html So with all that information in hand I need help and a fix for this. People also said to try this bambi fix which I had to hunt this page down because not it gives a 404 error. Also because the post had a ref to this fix more or less this is the fix posted on the bambi site.



First, disconnect your battery.
Behind the passenger kick panel on your late-model F-150 is your fuse box. Pull the access cover off, locate the relay in the top center and pull it out. (Relay 202 Fog lamp relay)

To make your fog lights stay on with the high beams, you need to provide a permanent ground to one of the pins. At your work bench carefully bend over the tab you see in the photo above. Try to be gentle but bend it over so that it nearly folds over on itself and follows the contour of the relay case. Then get a length of wire (I used 20g) and crimp on a female blade and stick it and the attached wire on the relay pin you folded over. When you're done you'll have what you see in the photo above. (Will post the photo of the relay from the bambi site.)



Before you push the relay back into the fusebox, use a side-cutter to nibble away or notch the plastic to the right side of the relay socket on the fusebox to gain clearance for the folded over pin. Then pop in your relay and make certain that it is secure.

Now locate the green grounding bolt located below and rearward of the fusebox. You'll want to pull the door kicker panel partially out to gain clearance for more space to work in (that pannel has two two clips: pull straight back and the panel will lift out of the way). Route the lose wire coming off of your relay behind the big electrical plug on the rightside (rearward) of the fuse box, cut off the excess wire and crimp on an eyelet. Remove the green grounding bolt and reinstall the bolt with your grounding.

Quick Edit: My 202 relay doesnt have three pins at the top only the two outer ones so its a four pin not five pin...

 

So I ended up biting the bullet because I haven't had any replies just did the Bambi Mod and it fixed my issue though now my fogs don't turn off when my high beams are on but whatever small price to pay that being said I am going to post the Bambi mod here because the original website shows a 404 error now.

If you live in a rural areas you understand the necessity of throwing as much light down the road to light your path and spot any critters in lemming mode that are waiting alongside the road to end it all by casting themselves in front of your cruel tires.

Nowadays there are government laws that require manufactures to turn off OEM fog lights when the high beams are switched on. Annoying since most people turn on their high beams because they want more and not less light. All the more unfortunate since late-model F-150s leave something of a "dark spot" right in front of the vehicle with high beams on that the fog lights would illuminate well.

After hitting five deer, one skunk (that was bad), a porcupine, and whatever else, my contribution toward animal conservation was to convert my fog lights so they stay on with my high beams to help me better see and swerve around the little buggers that dive out in the road.

This is how it is done with 2004-2006 Ford F-150s:

First, disconnect your battery.



Behind the passenger kick panel on your late-model F-150 is your fuse box. Pull the access cover off, locate the relay in the top center and pull it out. (In my 2007 it was relay 202)



To make your fog lights stay on with the high beams, you need to provide a permanent ground to one of the pins. At your work bench carefully bend over the tab you see in the photo above. Try to be gentle but bend it over so that it nearly folds over on itself and follows the contour of the relay case. Then get a length of wire (I used 20g) and crimp on a female blade and stick it and the attached wire on the relay pin you folded over. When you're done you'll have what you see in the photo above. (I personally had no center pin so my relay was four pins not five but it seams in all cases its pin 1 you need to bend I also used 14g wire to be safe and heat shrink around all the connections and electrical tape.)



Before you push the relay back into the fusebox, use a side-cutter to nibble away or notch the plastic to the right side of the relay socket on the fusebox to gain clearance for the folded over pin. Then pop in your relay and make certain that it is secure.


Now locate the green grounding bolt located below and rearward of the fusebox.

Route the lose wire coming off of your relay behind the big electrical plug on the rightside (rearward) of the fuse box, cut off the excess wire and crimp on an eyelet. Remove the green grounding bolt and reinstall the bolt with your grounding wire.

Button the two panels you pulled out of the way back up, and then connect your battery. You're done and should feel pretty good about yourself because your fog lights will now stay on with the high beams!

 

Nice write-up!
