Electric Testing Techniques You Need to Know

Hi. Thanks for your question. For the diagram of Tail Light you can visit https://www.reliable-store.com and download the entire workshop manual. It has all the information along with the diagrams for better understanding. Good day!

Should be on the same fuse. If you have no voltage to the tag light socket, check the wiring especially where it connects to the tail light harness.

The license plate lights have their own separate bulbs. If you are able to replace the bulbs, that may solve your problem. If not, you may have a loose or rusted connection to the plate bulbs only. If you are able to gain access, you may want to check the condition of the harness that supplies the power to the license plate portion. Good luck and have a great day.

Look for short in wiring within the wiring harness. Had same problem and found 2 wires shorted together

These are the diagrams basically from the headlamp switch going back to the license plate lamps. The main splice after the headlamp switch going back is in the main harness near the warning chime module. If you need a larger picture or the entire outside lighting wiring, feel free to email me at [email protected] with all your vehicle information. Yes it is that simple by just splicing into the main rear light wiring at the brown wire. Hope this is what you were looking for.....

Hi
There are a couple of wiring diagram and manual available on the net. The relay you are talking about is the park lamp relay which supplies power to the tail lamps, license plate lights and both front and rear park lamps. If the park and plate lights are working the light switch, relay and supply power are good. You need to verify for a broken brown wire to the tail lamps (assuming the sockets, lamps and grounds on both tail lights are good) .If none of the lamps are working then the 15A fuse number 3, the light switch or the park lamp relay could be bad (note different contact in the main light switch work the other lights)

You can find a wiring diagram and component location at

1. Disconnect and isolate the negative battery cable.
   
2. Lower the tailgate.
   
3. Remove the two screws that secure the tail lamp unit to the cargo box.
   
4. Remove the tail lamp unit from the cargo box.
   
5. Disconnect the body wire harness connector from the lamp back plate connector.
   

To install:

1. Connect the body wire harness connector to the lamp back plate connector.
   
2. Position the tail lamp unit into the cargo box.
   
3. Install the two screws that secure the tail lamp unit to the cargo box.
   
4. Raise the tailgate.
   
5. Reconnect the negative battery cable.
   

Oh boy, Chevy uses 3 important wires to make up their tail light harness. Brown is used for your parking lights and yellow and green are your signal and brake light wires, yellow one side, green the other. You have some seriously crossed wires. Start with tracing the lic plate lite since that works. Make sure it leads into your main parking lights and the ground wires from these tail lites aren't cut. The lic place lite will work with just power because the body of the lite is grounded with the bumper. Then make sure that there is power to the signal wires. You can do this with a test light and the signal light switched on. You don't need anyone to step on the brakes since it's the same signal, only interepted. Most importantly, Remove the tail lites and check grounds!! Good luck

I'm assuming you're just going to splice into the tail light wiring so that's what these wire colors are:
at the tail lamp 3 way connector:
black and yellow = park lamp
dark green and brown = left turn signal
there should be another connector with violet and black wire for reverse lights.
the stop lights are turned on through the turn signal circuits.
