Default Fogs lights on the fritz

In putting together my truck for the "stage 1" of the build, i replaced both fog lights. Both worked. I was happy.

On the drive home from picking it up from the alignment shop, both died. At once.

I've checked: Fuse, both relays, switch. The fuse is good, the relays are both tripping, and the light on the switch is working. (I realize that the light on the switch can work, but the switch itself be messed up, but if that were the case, i'd imagine the relays wouldn't be tripping.)

There is no power making it to the fog light pigtails.


Is there a common failure point here? Or am i looking at a horrible experience in trying to unravel and trace back wires potentially all the way to the relay box?

I'd just check continuity through the wires with a multimeter, and if they're bad just run new ones. Or you can try using the old wires to pull the new ones through the harness, no guaranty that'll work though.
