2004 GMC Yukon Black & Smoked Tail Lights

I like these lights they look really good. The original driver and passenger side tail light the original wiring is self explanatory. But if you buy and change them to these the wiring is different the bottom wiring harness for the original lights goes on top and the top goes to the middle and the original middle wiring goes to bottom other wise everything will be out of order also I had to cut and add wiring to the passenger side because of the flip from bottom wire to top hope this helps other then that lights are awesome and definitely make a difference.
