S10 tail light problem

[MT-2500]

If you would do some testing and find out where the wire is bad you should be able to repair the bad spot or wire around it.
And save a couple hundred bucks.
Good luck

These will work.

CHEVY S-10 TAIL LIGHTS PROBLEM RESOLVED...It seems Chevy engineered a ground shorting clip located under the left rear bumper area. It looks like a connector for trailer wiring harness, but in actuallity is a metal shorting clip which ties 5 wires together. They are all the ground wires for the tail lights. Then one single small wire runs to ground completeing the circuit. Problem is that this one wire is not tough enough to be a strain relief for the grounding plug and over time the ground wire wears, leaving intermittent lighting problems. FIX IS TO SPLICE THE GROUND WIRE INTO ONE OF THE FIVE OTHER WIRES AND USE PLASTIC TY WRAP FOR STRAIN RELIEF. This fixes no tail lights, intermittent rear signals, and other significant problems. I just got done making this same repair on a 2000 s-10 and everything works fine. Since it is the strain on the single ground wire connected to the connector that leads to failure, it is best to tie a new ground or clip the ground wire coming out of the plug and resplice it into one of the other five wires. Does not matter which one since electrically it makes no difference; they are all gound wires. BUT only one wire completes the connection and that is the problem. Really good engineering Chevy!
