New to the group and still learning how to navigate. I have a 2001 Dodge Ram 3500 it had the single headlight bulb I am changing it to a sport headlight assembly. I am going to put LEDs in it 9004 and 9007 do I need to add a relay wiring harness and if so does someone have a diagram?

 

Upgrading to the sport headlights is probably the best way to enhance night time headlight visibility, short of adding additional lighting/light bars. I've performed that upgrade on my '96 Ram 2500 4x4. As for the harness, its best to take the load off the failure prone/overloaded factory headlight switch and install a harness with relays. I took the easy way and ordered this harness - https://ceautoelectricsupply.com/hea...ion-relay-kit/
