Boat Trailer Wiring

I need to add orange lights on the side of my boat trailer, which has four poles wiring flat. Yellow lights have only one hot wire and "automatic" on the ground, connected to the frame. Do I just type in the thread of light running with the light yellow brown wire to live? This does not seem to be a complete circuit for me, but there is a wire connected to the bulb, so I see no other way to do it. Thank you!

is exactly that, just make sure that the screw that is a ground goes bare metal on the trailer

You will need a current tester 12 volt, put a hole in the wire liitle with the pointed end of the tester Make sure that the testers to land. Turn on the lights and find the son of light running, mark them with tape .. After that follow the light and join the son of light running .. he welded inside the pot and do light water gets on them, a band with zap straps to keep electrical.Use son neat.Check \ hook new light on the son to make sure they work / make sure they are grounded when you test them.

Yes brown wire is on the right and the soil structure in place before the white wire from pin 4 should be the ground wire attached to the trailer frame, the link is more than you think
