How Do I Install Load Resistors for the LED Lights on my 2007 Dodge 3500 Flatbed

Question:

I have a 2007 Dodge 3500. I have a CM Flatbed on the abck with 4 3x5 LED tail lights I ordered. When I installed them It threw the light out chime/error code when I brake and when I use turn signals. I ordered 4 Resisters for Superbright LED.com. I am wondering if I just need to hook 1 to left turn and 1 to left brake and them same on right side to remove the error code.... Also I have heard about people wiring in a normal light under the bed so there is resistance on the computer... I am just wanting some advise. Thank you

You will wire a load resistor into the wiring of each light socket that has an LED bulb and flashes. So basically you will need to wire a load resistor into any bulb that blinks or has a dual intensity feature that lights up when the brakes, blinkers, or emergency flashers are operated.

To do this correctly, you will need to wire the load resistor on the positive wire and then either ground it to the ground wire of the bulb, or to a good frame ground. You will need to do this for all of the LED bulbs that blink with the blinkers or flashers, and that illuminate brighter when the brake is applied.

Installing hidden lights on the circuit will also clear up the problem too. You would have to install a bulb on every circuit though, and if the bulb blows the lights will not work properly and you will see error codes again.
