So I just installed my 4 inch led lights in place of my fog lights. wired one up, worked. wired the second one, now neither work.

-The switch is pulled towards me
-Checked #21 fuse and it is good
-The fog light indicator lamp isn't on while switch is pulled.



What the heck?! I'm stumped

 

pics of said fogs

 

might be dumb but start simple... is the switch in the auto mode. if so just move to manual and it should work if not check voltage at the plugs.

 

Yeah nothing in both auto and manual mode. Haven't checked the voltage at the plugs, but even the bulbs i had in the fogs before aren't working.

 

my book say fuse 47 is for fogs its a 15amp in the truck not under the hood

 

47 on mine is a giant metal fuse thing

 

on mine 47 is the one on the lower right corner. might just check that one to compare. I see yours is a 2011 fx2 right?

 

Are your high beams on? the fog lights go off when the high beams are on.

 

Yep! 47 on mine is in the upper right corner. My high beams aren't on.

 

ok I figured out the mix up with the wiring differences. yours has the same wiring setup as the 2010's.
