Nice clear pictures! You might run into some problems hooking up your taillights,as your suburban probably had seperate brake lights and turn signals. If so,it's going to take a little more work hooking things up,if not, you are good to go. As far as what you have pictured, hook the black taillight wire to the brown harness wire for parking lights,and the red to the green wire for turnsignals. Black on the harness is generally backup lights,the other wire in your photo looks to be white,and could be a ground. Hope this helps you, Hank
