Sorry for the late response. I was able to locate the problem. I have a 4-round male adapted coming off of the trucks harness. I have a 4-round female plug on my trailer that I use. I bypassed this and hooked up my trailer directly to the truck's harness. Fixed the issue.

Using my volt meter I was able to find out that the 4-round male adapter on the truck is wired incorrectly which is casing the short.
