Running Lights acting weird

[1997k1500Calvin]

Ok I have a 99 nbs extended cab, 5.3.. ,when.I press the brake it lights up my turn signals even in the front, when I turn on the blinker it lights up my brake lights, and if I brake and hit the blinker they flash really fast like a bulb is out...any ideas?

live action!!

Start by disconnecting your trailer harness if you have one. Sounds like a brake light wire is shorted to a running light wire.
