I was looking for the wig wag light module that is installed to activate the flashing alternating lights. The upfitter guide says it's installed on the radiator support on the passenger side but I can't find it. I applied 12v to the green wire in the harness to activate it but nothing happened. Is there anywhere else it would be or does someone have any pics of one? Maybe with a part number? I'll be looking to add one if mine was removed.
