    The flasher, turn signals and brake lights all go through the turn signal switch prior to going back to the bulbs. The parking lights all are a separate circuit fused by a left side and right side. The only place in common is your pigtail connector for the trailer. Look where your pigtail connects to the tractor and possibly there is a loose wire shorting. The other place I would look is the turn signal switch itself. It's not uncommon to have more than one problem when getting someone else's problem. :)

    Check them parking light fuses first. You should be able to get them working first unless the other circuits are shorting to them in the pigtail connection.

    Here's a pdf schematic, enlarge it to see better.
