So on your 2013 Toyota Tundra 7-Way trailer connector there is no wire in the back at the 7 o'clock position? If that is the case all you will need to do is get about 20 feet or so of wire # 10-1-1, sold by the foot, attach it to the back of the 7-Way in the 7 o'clock position, then route it under the truck, into the cab, and attach it to the blue wire coming from the back of the controller.

When routing the wire avoid areas that can pinch or burn the wire. You may or may not have to drill through the firewall to route the wire into the cab. If drilling is needed be sure the area on the opposite side is clear.

Sever the blue wire at the end that plugs into the truck and attach the wire to it. This method bypasses the factory wiring, which apparently is not present on your truck for some reason, allowing the brake controller to send back power to the brakes.

If the absent wiring is an issue on the trailer side then again you can use wire # 10-1-1 and attach one end to the back of the trailer side connector in the 5 o'clock position and then to the trailer brake magnets.

If you need wiring installation tools and connectors you can use # HM51010.
