Not trying to be a dick here but I have been installing hitches and wiring vehicles since around 1992. Please see attached prodemand schematic. Can you please show photos of what you've done? There's also sometimes a light blue run to the rear. This is only to be used for brake light on let's say a cap. Our trucks have same turn and stop bulbs where some need the 5 way convertor to get you down to the normal trailer 4 way.
