Nothing has been officially diagnosed...everything so far has been a guess (IMO). Keep in mind this drivetrain issue is not arising 100% of the time. Earlier today I got a call from my s/a saying I was being charged $180 for their electrical guy to come check my work because they thought that was the issue. Fast forward to just now, I get a call back saying my lighting setup was perfectly fine, no issues there. However, one of the through wires wasn't fully covered by the electric tape that came on it originally and that was the source of the problem, after re-taping it they said my truck runs perfectly fine and they believe the issue has been resolved. I guess I'll just have to wait and see what the hell happens, I'm still very skeptical that a drivetrain issue is being caused by an exposed through wire.
