Does the 12 Volt Black Power Wire Need to be Run with the Curt Echo If There Is No Trailer Battery

Question

Question:

I have a 2018 Highlander trying to tow a 19ft pop up camper. I have the factory installed hitch and 4 pin harness. Im thinking of ordering the ETBC7 and the Curt Echo. I know I cap the brake controller wire, but what about the 12 volt wire? Do I have to run it to the car battery? If I dont have any desire to charge the aux battery on the front of my camper, does it serve another purpose? Does the Echo require it to run?

For starters, if you will be using the Curt Echo Mobile Trailer Brake Controller part # C51180 then I recommend the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation part # ETBC7L instead of the Universal Installation Kit for Trailer Brake Controller part # ETBC7 as you can save some cash this way. The Universal Installation Kit for Trailer Brake Controller has extra wires that you don't need.

In regards to the black 12 volt power wire, this will need to be run if using the Curt Echo Mobile Trailer Brake Controller because that is how the unit receives power. If you are using a different brake controller like the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 but will not be charging any battery on the trailer or using the 12 volt accessory then the black 12 volt power wire will not need to be run but this one will require the blue brake output wire instead.

Therefore, you can either choose to run the 12 volt black power wire to the battery for the Curt Echo Mobile Trailer Brake Controller or the blue brake output wire into the cab for the Tekonsha Prodigy P3 Trailer Brake Controller. I will say the 12 volt black power wire will be an easier option than the blue brake output wire still as you also have to make connections under the vehicle's dash for the brake controller as well.

You did install the 7-way bracket of the EcoHitch part #EH97FR that fits your 2022 Toyota RAV4 correctly. It is an odd angle that the 7-way does hang at. You could maybe try bending the bracket back so that the angle is better or you could use a…

Answer 5

When mounting 7-way brackets you actually don't want to attach to the frame of the hitch by drilling into it. The best place to attach the bracket of the #ETBC7 that holds the 7-way should be on the bottom of the rear bumper.

Here's what I'd recommend. If you have an exposed portion of the hitch crossbar to work with, use the #18136 no drill bracket. This fastens to the hitch crossbar using an included pipe clamp. You'll also use the #PK12711U 7-way mounting…

As far as the mounting bracket, you can absolutely screw it directly to the hitch if you want. We do this frequently in our own installs and it will not compromise the strength of the hitch in any way. Now putting a few holes in the hitch does open…
