check ground wire on rear of frame for Chevy trucks
The ground wire at the bulbs is black.
The most common cause of taillights and â?? lights not working is a bad ground wire. The ground wire may be broken or the connection is corroded.
That usually means one or more of the bulbs is not working. Check for bad bulbs or bad ground wire or socket.
Easiest way is to connect a single wire from one of your rear taillights "parking light" to the wire on license plate light. It gets its ground from the bumper once installed.
Could be a bad ground or bad wire leading to the tailights possibly a bad brake light switch.

The entire lighting system is grounded to the frame of the vehicle. If the ground wire is not connected properly, or if it is corroded the lights will not work.
You have a grounding problem at the trailer. The white wire is the ground on trailer wiring. The taillights are brown, the signals and stops are yellow and green. Sometimes the white wire will loose its continuity with the truck, causing the lights to black out. It could also be a wiring issue with the trailer itself, but most likely its the ground giving you feedback and causing the blackout. run a wire from the ground contact on your plug back to a spot on the tongue and secure the end of the wire to the trailer at that point. Do not rely on the contact of the trailer with the ball hitch to establish a ground.
You can find the 2005 Ford Ranger radio CD player wire color codes in most service manuals. The wire colors are associated as follows; the positive wire is red, the black wire is the ground, the green and yellow wires are speaker wires, and the white wire is the auxiliary wire.
It means a wire in the ground.
