I've search on this fourm and online and no answer, I installed led lights all around and now need to change my flasher, however where is says in manual is incorrect, unless I got the wrong relay. It says in cab fuse pannel #1 howver that is a small relay half the size of what I got from napa, I have also read its not in fuse pannel and tucked under steering coloum I looked and can't find anyone know what's going on... Its a 98 F150

 

The flasher relay is located in the Blower/Flasher Relay Block, behind and slightly to the left of the center of the instrument panel. It is not in the owner's manual.
