Hi Friends! I have a 2010 FX4 F150 The front right turn signal is not working. The rear right turn signal is working, also the mirror turn signal light is working but faster than normal. First thing to check was the bulb and it's working.

As I installed and AMPLIFIER and I run a 4Ga cable from the battery to te rear set thru the firewall barrier. I'm affraid I broken something when I made the hole in the large arnes gromet located just below the computer.

I'm looking to get the related wiring diagram in order to trace the problem. Thanks!
