I've been doing a major modification on my 2010 Ram 2500, as you can see. I took the bed off and mounted a dumperdogg dump bed on and some tool boxes on where the side panels/wheel wells were.

Now to my problem. I needed to replace the whole lighting system in the rear (brakes, turn, reverse etc),so I bought 2 Multi-Function LED Truck & Trailer Combo Boxes to mount on the on side of the toolboxes. I got it all wired and everything works fine IF I have the truck on the "AUTO" lights setting. If I switch the lights on manually the blinkers/hazards will not work. It seems when the "running lights" are on the blinker doesn't work or register.
Any thoughts?
The Combo Box has 4 wires: Red: Red High; Brown: Red Low; Yellow: White (Reverse); White: Ground
