There is a Standard Wire Color Code...
...and then there is Keystone. The plastic license plate mount tabs broke on my taillight so instead of replacing, I built a bracket on the rear bumper to re-mount the license. I used LED license plate bolt lights and decided to run the hot and ground back to the junction box. I opened the box, found the brown wire connection and cut, soldered and heat shrink'ed the two original wires and my new third wire and tied the ground to ground. When I applied power to Pin #1, the running lights were on but no license plate lights. I started probing with a meter and found the green wire coming in from the seven pin is running lights which is connected to a green wire going into the trailer. The pinout is correct, but the color code is NOT standard. I should have verified the pinout an color code first I guess, but who would have thought the color code would be wrong?? Lesson learned. I re-did my work to non-standard and now have license plate lights. Brown is right/turn stop on my trailer, except for the brown wire going back to my license plate lights soldered to the two green ones! So much for a standard.
