Pillar suppose to just pop off. I had a hard time trying to take mine off. Was afraid I was going to crack the pillar, so I went back to the wiring harness behind the passenger seat. Lights came with a red and 2 browns. Tie one brown into the brown/pink, the other into the brown/gray, and the red into the black and yellow with white stripes in the harness. Youll have to dig for them, but they in there! I used a flashlight to shine directly on the wires to see the colors better.. Maybe Im getting old and eyes not too good anymore but worked for me! :-)
