If it's intermittant, it will be hard to find. It's possible it has a wear point, and you might find it by looking closely at the harness. You'd have to remove it to look all of it. Look for rust stains on the insulation, or green corrosion from exposed copper wire. Any break in the insulation could be the culprit. You could try to pull the harness one way or the other to see if you can move it away from the wear point. Might be cheaper and less time consuming to buy a whole new harness, and reroute it. Use a fish tape to route it through the frame rails. You could also tie some string to the ends of the harness your taking out to inspect, and use the string to route the repaired, new harness. Good luck.[/QUOTE]

Definately a short somewhere. Does it always happen, or is it intermittant? Had a friend who took out a blown bulb on one of the side markers, and didn't replace it. The contacts touched, and he had his whole harness out when I came over to help. Found it right away, and spent the next hour fishing the harness back through the rails.
