Ben, please take the time to watch ALL of the wiring videos, old and new, paying attention to where the brown twisted high speed LAN wires (and the green twisted low speed LAN wires) get cut, and eventually get tied together. As @Ark :D just mentioned the harnesses get combined and it's in this process these LAN wires get tied together --brown to brown and green to green. We are trying to help you through this and please know that 350+ other builders have been through this before you and have successfully completed their wire harness work. Keep the faith!
