I'm helping a buddy put new trailer lights on - and his aren't color coded. How can you tell from the 4 wire harness in the new light which color is what? For example the left side trailer light also has a clear part under so the license plate is light. It has the following wires:
white green yellow
The right light does not have the yellow but has a green
white green red
When I go to hook up my wires - which one goes where?
