Hey guys I got the solution you've been looking for if you want your fog lights on with your high beams. Remove the half ISO relay that controls your fog lights. Cut terminal number 1 leaving about a 32nd of an inch remaining. Solder a wire (doesn't have to be a huge wire its only about a 1/4 of a volt, I used 22 gage wire) to the remaining piece of the number 1 terminal, get the wire insulation as close to the terminal as you can to avoid accidental shorts. Place the relay back in its spot and ground that wire you just soldered. ENJOY!!

 

Just curious, why do you need fogs and high beams at the same time?

I would love to be able to use fog's and high's at the same time. We have a house in the interior of BC and the main highway is really dark at night. The farther you can see ahead the better.

 

I understand the use of high beams, the fogs don't help see far up do they?

 

2 methods, search would have found it. BTW : no need to clip the relay terminal:

Oh now you tell me. All the head scratchin, trying to figure out wire diagrams, understand how that relay works. That way would also be a little harder getting that fuse panel cover back on. OH well I gotter now. Thanks again for your help with my previous problems. Don't know how the '05 and '06 main fuse panel was put together but the '08 is all PCB.

 

With the new body style truck, if you are not adverse to the look, take a look at the Hella gille with the 5000 series light heads in it.

I just installed one of these on my truck, and used the Sylvania SilverStar H1 bulbs for it, and WOW is the only description I can use.

When I turn on the high beams, the distance is quite incredible with this light head design ( reflector and bulb type ).

Although it is designed to look like the grille in the new Mustang, they are not fog lamp reflectors.

 

This is indeed a good mod to make. (and cheap!) But its hardly new. Here is a good writeup that I used when I did my truck

I have been trying to find that page for about a month now and couldn't find it. I did this mod to my 2005 and couldn't remember how I did it. Thanks anyway, I saved it to my favs this time.

 

The more light the merrier.

Seriously, I hate how the highbeams - without the fogs - basically kills the lighting up close, immediately in front and to the sides of the travelling vehicle.

Fogs with HB's at the same time resovles that issue very nicely.... especially with correctly aimed/adjusted fogs.

The results are day-n-night.

 

Couldn't agree more. I am getting ready to add a bullbar with some lights. Hopefully something bright and hot enough to melt the paint off the next jack@$$ thats pulls out in front of me, and if I am lucky it'll be pitch black dark.

 

this is a great mod especially for anyone who has HID hi/lo's and their highs turn on with their fogs. its an annoying problem HIDs create but this is a great easy fix

 

In the thread when someone pointed out this mod ( didn't catch it in the electrical section for some reason, so i re-invented the wheel, with a little flat spot on it ), I also redid the EVTM page for this mod.
