Re: trailer lights
Hello,
I just bought a complete trailer lighting kit from Walmart and will be installing it tomorrow. After looking at the directions on how to install, you are correct on your assumption.
Black/Green Passenger side, and Yellow/Brown Driver side.
Brown/Black are the running lights.
Word of advice, ensure you your grounds for vehicle/trailer (white wire out of wiring harness) are connected to solid ground. This was the problem my Dad and I were having trying to get my old lights to work before we bought the new kit. A good tool to have handy is a voltmeter, which is how we discovered our issue.
