There will be no default power going to your trailer's brakes without a brake controller on your 2020 Toyota 4Runner with the factory 7-way. So in order to activate your the brakes, you do need to have a working brake controller; thankfully, with your '20 4Runner with the 7-way, these are just plug and play so installation is simple.

The brake controllers I recommend checking out are the Tekonsha Prodigy P3 for the best overall brake controller, or the Draw-Tite I-Command for the best budget-friendly option that retains high quality.

The parts you need for each are the following:

- Tekonsha Prodigy P3 Trailer Brake Controller # 90195 with Custom Wiring Adapter # 3041-P

- Brake EVN # TK63VR with Custom Wiring Adapter # 3041-P

A factory 7-way trailer connector isn't all you need to power a trailer's electric brakes. You still need a brake controller. Some Ford F-150s are equipped with a factory integrated brake controller, which you may have. If your 2012 Ford…

The Curt Echo Trailer Brake Controller #C51180 won't itself provide any charge to your trailer mounted battery, but you certainly can still have a 12V power wire ran from the 7-Way to the battery for this purpose with the Echo in place. The Echo…

There is not going to be a 5 flat that has 8 wires; the functions of the 8 wires are likely ground, running light circuit (split into 2 wires at the plug), left turn, right turn, brake lights (possibly split at the plug), and output to reverse…

This sounds like a ground problem on the right side. The turn signal not working makes sense because with the brake lights, there is a constant signal coming through which is enough to make the lights illuminate on both sides like they should. But…
