Finding the Blue Wire and Brake Controller Installation on a 2011 Toyota Tundra

Question

Question:

Hi, I have a 2011 tundra base double cab with a tow package and 4 pin flat. I want to connect a 7 pin round to the rear of the truck. I purchased the adapter to plug into the 4 pin. I need to ground it, hook up power cable, and blue brake wire but I cant find the blue brake wire under the truck to splice into. Any advice as to where it could be? Thank you!

If your 2011 Toyota Tundra has a towing package but only a 4-flat you may not have a blue brake controller wire. The package with the factory installed 7-way trailer connector on the rear bumper included the plug under the dash, as shown in the photo I've attached for you. However, not all models with the factory 4-pole (or 4-pin) trailer connector will also have the plug under the dash, you'll need to look for a white plug located above and to the left of the emergency brake pedal, above the toe kick. This is the port the item # 3040-P you were looking at connects too. Occasionally, the plug will be located behind the toe kick, so you might need to remove it to find out for sure. If your truck has the 4-pole but no tow package connector under the dash, you'll need to hardwire the controller. This would explain why you have been unable to find a blue wire.

I am not sure what adapter you have but to add a 7-way connector to your truck you will need the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires item # ETBC7. The kit includes a pre-wired 7- and 4-way trailer connector that mounts easily at the rear of your Tundra with an included bracket. This kit is designed for use on a vehicle with an existing 4-way flat trailer connector and plugs directly into it. This includes a brake controller wire that will run all the way into the cab of your Tundra. I have linked a video below of this kit being installed on an earlier model Toyota Tundra.

If you just want to wire your 7-way to your existing 4-flat and run the power and ground you will still be able to use a brake controller on your Tundra. The Curt Echo Wireless Trailer Brake Controller item # C51180 does not require you to run the brake control wire. I have linked a review video below. So long as you have the 4-flat connector and the power and ground hooked up to your 7-way the Echo will work perfectly with your Tundra.

Answer 6

I'd recommend using 10 gauge wire like part #10-2-1 (sold by the foot) for the brake power and ground wires as this will be more than adequate and will ensure you get plenty of amperage to activate the brakes.

All the brake controller needs to sense a trailer connection so that you can test it is a slight amperage draw on the output circuit. For that you can use a circuit tester like the part #PTW2993 with one pin grounded and the other on the output pin.…

Answer 11

Yes, 14 gauge wire seems too small. I would go with 10 or 12 gauge. For 10 gauge you can use #10-1-1 and for 12 gauge use #12-1-1. These wires are sold in increments of 1 foot. So if you needed 20 feet of wire you would enter 20 in the quantity box.…

Answer 12

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
