Default tail light and left running light problem

Ok,my tail light and left running light have no power,brake light,turn signals and right running light working fine. No visible breaks or exposed wires. If I switch my right running light connector to left it works.No cold solder joints on tail light board. 2009 Road King with ABS. (USA model) All worked fine when certified a month ago. No mods done or added to lighting.

Electrical "gremlins: can drive you nuts and sometimes are simple fixes.
Re-check your bulbs. Wipe and clean he sockets and apply dialectic electrical grease in both sockets.
Since you didn't include your RH running light, you may have a bad or no ground for non-working lights.
You need to pull the non-working bulb(s) and use a test light to determine if you have no power or no ground.

You can always resort to the "jiggle, tug and push" on your wiring harness (with the lights on) to see if you can manage to get a flicker of where your problem may be. Another think to try if you an locate any connector plugs is to disconnect them and apply some dialectic electrical grease just to sure that you're getting a good connection.

Mine drove me nuts. Lights not working, speedo jumping... all kinds of weird shlt. I found that it ate my wiring harness and I repaired it. That was the last thing I checked after connections, bulbs, fuses (which blew), grounds... everything.

I finally reserved myself to buying a new harness and shocks. It took a few days to get the parts, but it’s back together and better than new.

basics first.

Ok,by-passed this unit (disconnect unit and it connects directly into rear harness connector) and everything except signal running lights work now. Going to get replacement but doesn't show up on wiring diagram that I can see. Can someone give me the name of this?

How can you be so cruel as to post something that just reading it is hard to figure out? Then get the solution and keep it to one's self. At least 3 deserves the solution. And what if I have the same problem!?
