The tail lights were a breeze. They're plug & play. I got them off of ebay (link below). I never heard of the cruise control issue, but I'll try that today. The tail lights have the three bulb wires (brake, turn, reverse) coming together to one roll which then goes through a rubber grommet and ends at a plug in harness. The LED replacement is the same way. You just unplug the harness, remove the rubber grommet, and install the new one, simple. The only hard part was the driver side panel. You have to remove the jack cover, door sill cover, net anchors (only two at the back), take off some of the rubber door-seal, and pry the panel back to get to the harness. The passenger side has more room and was much easier. In all, took about 1/2 hour. Good luck.
