Is There a Wiring Gauge Minimum for LED Trailer Taillights

Question:
Hi, I am wiring my 13 ft 1981 Scamp camper. I ordered the Optronics led 7 in tail lights for 12 volt. I want to be sure that the 4 way harness I purchase has the correct gauge wires. I see that there is variability among the harnesses here. I do not have a battery or any other needs. Also, if the wishbone comes with 2 brown wires, can I still run the green wire with the yellow until I reach the light fixtures in the back? I would just use one brown for the passenger front marker light and run the other brown from driver front around to passenger back hooking to markers and tail lights on the way. I am fine if the harness is not a wishbone as well. Is there a particular harness that you would recommend based on my needs? Thank you

Hey Rhonda, since your taillight kit is LED and they draw a very small amount of amperage you really don't need to worry about the gauge of the wiring of any of the kits we have as they will all very easily power LED lights like the Wesbar part # 002220 that you referenced.
You can run multiple wires to the single brown wire of the # 002220 to power the running lights as well.

Hey Rhonda, did the Wesbar wiring harness work out for your Scamp camper? I'm curious to know if it met your needs, as it could help others with similar projects.
