For your # HM56200 the first thing to check is to make sure everything is grounded.
1. The connector on the vehicle should have a ground wire secured tightly to a clean surface on the frame. A wire attached to the body or a surface with undercoating or rust can cause a ground problem.
2. The connector on the trailer should have a wire from the connector secured tightly to a clean surface on the trailer.
3. Each tail lamp assembly at the back of the trailer also must be grounded. This is done in one of two ways. The first is by a separate wire coming from the back of each tail lamp assembly being secured to the frame. The second, and most popular, ground is achieved through the bolts of the tail lamp assembly. In this case, the lamp housing must be attached to the frame of the trailer. If the lights are mounted on wood or PVC material, the light will not receive ground.
Next check to make sure each connector is clean and free of debris and there's no bent or damaged pins in the connectors. The pin that transfers the signal for your brake lights could be dirty or damaged. I recommend using # 11755 in the connectors to prevent corrosion and and water damage.
If the brake and turn work from separate bulbs, the design is independent. Vehicles will vary depending on the make and model. Any vehicle that has an independent bulb system must have a converter to “convert” the independent system to a common which is required on a trailer. A converter enables vehicles with independent brake lights and turn signals to provide proper lighting to the trailer. For this I recommend # HM46370.
If after all of this you're still having issues then the wiring kit you have may just be faulty.
