I suspect you only have the large plug brake controller harness and you are looking at opposite ends of the same cable. The large plug cable is wrapped up with the main wire harness so it is hard to trace without removing all the tape. The large plug cable plugs into a socket next to the main harness junction where the harness passes through the firewall. The same style plug is used on both ends. I've supplied pictures of the cable where it plugs into the main harness. I would use a volt meter to confirm this.
Unplugged at the junction.
