I've done the headlight upgrade harness, followed the instructions but something is not right. Turn on the running lights ( position 1 ) and I have side markers, tails, front driver headlight and front driver running lamp and no turn signals. Turn on headlights ( position 2 ) and I have all lamps, no turns, and no driver high beam. Anyone run into this?

Have you tried sending a PM to Dave, aka Zs-ondabrain? You apparently miswired something.

You didn't perchance plug the new harness into the turn signal/marker light 3-prong connector rather than the head light connector on one side did you? There should be no inter play with the turn signals!

Either that or you have a very strange wiring issue with your switch..
