    Looking for help as to what color wire to test for power. I have a 98 2500 with working stop,haz,turn, and reverse lights. Both tail lights are not working and yes the bulbs are good.

    did you lose your marker lights in the front as well? if so it may be the light switch itself- i know on my pre '95's that was the issue on 2 of them unsure of the '95 and newer

    check the harness in the back for corrosion. if there is a ground make sure it its clean and in good condition. go through the fuses, my 92 would blow weird fuses and the tail lights wouldnt work and it made me mad everytime!

    It may be the circuit boards in the tail lights. They are known issue on that era of trucks. I have replaced mine a few times in a '89. I stopped using aftermarket ones (Help! brand) and bought genuine chevrolet replacement part and my lamp issues have gone away.

    Thanks everyone got them fixed. In that vehicle the taillight wire at the 4 flat plug in the rear behind the bumper is the brown one. Between the front and rear of the truck it was broken.
