I just received my spot light kit from pro-drive. has any one on here ever installed one? I have the old set up for the light. I just want to know if i can take out the old screw in ports and just replace with the new ones that came with it. also can i use the wires that are already ran with out running the new wire? any help would be greatley appreciated?

Don't know about the existing mounting holes or hardware but if your wiring is still good there is no reason it won't power up just fine.
