Do you have a groud from the battery to the frame? I know you said the lights are all ground to the frame. I always run a cable from the engine to the frame.
Sound like the front harness may be your culprit, which is common. No need to run a bunch of uneccessary wires front to back for grounds. If it works normally with the front disconnected, I'd check the front harness from the firewall to the lights in the hood. Sounds like the left and right circuits are crossing in that harness.
