Off subject a bit. I just bought a Feniex Typhoon Full Function Siren. It has the integrated wig wag. I installed everything and it seems to work quite well but I have recently discovered that my 2012 Ford Fusion SE has a power wire running to both high beams. I'm trying to figure out how to isolate the headlights so that I can utilize the integrated wig wag without jacking up the factory wiring. If anyone can help, it would be greatly appreciated.
