Wiring a 2021 Subaru Outback to Use a Wireless Brake Controller


Hi - I am a real NEWBIE. My wife and I bought a Safari Condo F1743 and just took delivery. We both have duplicate 2021 Subaru Outbacks with factory installed hitches and 4 point plugs. The F1743 came equipped with a Tekonsha Prodigy RF brake controller and Remote handheld unit. We have been getting what I think is bad advice from some RV places, one being to replace the unit with a hard wired unit because the remote is subject to a lot of interference. Another was to ignore the 4 point plug and wire in a whole new complete chassis. Ive been reading and researching, and saw the ETBC7, but now Im going to the pros. Whats your advice on the best way for us to get on the road. Jon

To get both of the 2021 Subaru Outbacks pulling the Safari Condo F1743, you would need to purchase two of the # ETBC7L kits. They would piggy back off of the existing 4 pin connections already on the vehicles, so you are already partially there. The # ETBC7L would allow you to utilize the Tekonsha Prodigy RF controller, or add on a hardwire kit at a later date if needed.

There have been a few connectivity issues, but generally with larger vehicles and or motorhomes. One of the big pluses with the Prodigy RF controller is its ability to be moved between vehicles without having to plug anything in under the dash or mounting a controller to the dash.

Try out the Tekonsha Prodigy RF to see if it will work for your needs as it is a good controller. Hold on to the excess wiring incase a hardwired setup is needed.

I did include a link to an install of the ETBC7 on a 2011 Outback, but it would end up being almost identical to the install of the ETBC7L on your 2021 models. It is a technically a hardwire set up being done, but it would still be mostly the same install with the Tekonsha Prodigy RF.
