Hi, we have 1812 Classic P/N 1812-081 with the old CCTV Camera Kit 1812-147 that has the Wire Harness Terminals we want to update to the newer Kit that has the BNC and CCTV Circuit board just wanted to confirm the correct Procedure would we remove the old Wire harness and use the 2 power wires from the power supply and connect them to the new CCTV Circuit Board and then attached a BNC connector? Are there any other steps? I have  attached links to the 2 installation manuals
