check to see if any wires are damaged or got de-pinned from the connector.

Also check for corrosion at connectors.

I checked for corrosion and I pulled the socket out of my bumper then unplugged the socket and tested the plug then tested on back right to the wires and still nothing but rt brak/blinker only so what should I be looking for now
