This is the tail light assembly I currently have:
Using this right side as an example, it has 3 wires. Green-running, black-stop and brown-r. turn.
I have purchased new sealed LED assemblies. It also has 3 wires, black-running, red-stop and white-ground.
As can be seen in the photo there are two wires running to the double filament bulb, the black and the green.
On the new light the white ground is no problem, attach it to the body.
Black to the single bulb.
Now my problem, Do I splice the origional black and green together and attach to the red from the new light to give me stop and turn light? Somehow that just does not seem right to me. I may be overthinking this.
