Question:

HELLO I HAVE A 2019 GMC 1500. THE ONLY TIME I GET HYPER FLASH IS WHEN I HOOKUP MY TRAILER OR WHEN MY 60INCH LIGHT BAR IS CONECTED. WHERE DO II INSTALL THE LOAD EQUALIZERS...THE TRUCK ITSELF HAS LEDS FROM THE FACTORY SO I AM AT A LOSS HERE.... THANKS AGAIN...

Sounds like your trailer has LED taillights which unfortunately is causing your 2019 GMC Sierra 1500 to have hyper flashing blinkers when connected. The easiest solution is going to be the 7-way adapter part # C57003 which has the load resistors built in so you don't have to do any wiring. If instead you need to go from a 7-way to a 4-way you'd want the part # C35FR instead which has the same resistors built in.
