Question
Both the # 2 terminal and the #4 terminal turn on the left rear tail light.  Is this the way it should be?  If not, what do I look for and where?

Answer
Hi Ernie,

That's not normal. I would start by unplugging the wires to the tail lights at the tail lights and then use a 12v test light with just #2 powered to ID each rear wire. Then do the same with #4 and write down the results to see if the problem is in the harness or in the tail light assemblies.
