Fog Light Mod

Is there a way to have the fog lights stay on with the high beams on the 6.4L? I tried the search button but only found info for the 6.0 and 7.3.

It should be the same. The engine doesn't change the basic idea of wiring in the rest of the truck.

The wires and fuse box are in a different location, also many wire colors are different.

It's not that easy, on the 08+ there is a smart box junction and I'm not sure how to get around this.

Use a test light and find the right wires to make it do what you wanna do.

That is an option.

Yeah, its that easy, run a switched power straight to the lights. F the stupid box.

Back when I first bought my 08 F350 "XL" I wanted to install fog/driving lights, well I found that it had the harness for the lights installed so I ordered a set of lights, brackets and harness to the lights and the proper headlight switch, installed all of this and guess what? Doesn't work!!! After further investigation, not all smart junction boxes have the same relays, wish the parts guy would have known. Anyway, I wired directly to the 4th upfitter switch and have been happy. Just some FYI.

Brite box will do it.
