67castang

Just replaced the instrument bezel and dash trim on my "67" Mustang. The problem I'm having is that some things work and other things do not. For example, my left blinker works but my right one doesn't, the windshield wiper switch works, but my high beams light and brake light do not. I replaced several of the light bulbs and that didn't help. The old bulbs were 57-12v, the new ones were 57-14v. Any help/advice would be greatly appreciated. Thanks
