I just installed my new '10 bed on my truck as my original bed was a pile of rust. The new bed came with a new taillight harness which is plug and play. The only problem i'm having is that the right turn signal on the steering column turns on the left taillight and vice versa for the Left . The harness just plugs in without any problems and i'm assuming the factory harness is wired correctly. Any thoughts on what might be wrong?
