Electrical Problems

I have a 72 Charger and recently took the rear bumper and light assembly off for repaint. When I reconnected the wiring harmess in the trunk, I found that the rear tail lights no longer work with no blinkers or brake lights. When I turn the light switch on, the headlights and front parking lamps work along with most of the marker lights, but they no longer blink as directed. Also, the passenger side rear marker light does not work either as it is connected to the rear light harness. Could this be a flasher or turn signal switch failer? or something else? Any advie would be appreciated. Thanks.
