The left turn signal on my boat trailer is not working. I checked all the obvious things and found although there was power to the right side and to the running lights, there is none to the left. I have traced back the wiring to a little black box under the carpeting on the right hand side of the storage area. I didn't even know there was such a thing and I suspect it is the problem. What is this thing...it has wires from the car wiring compartment on one side and the wires to the trailer harness on the other. Is it something high tech and expensive or routine and easily replaced. If I'm wrong, what else could be the problem? I've checked all the obvious stuff like bad bulbs, corroded fittings, broken wires, fuses etc. etc. Any help/advice much appreciated. ds
