Question:

Have a 2019 Toyota Sequoia. I have a Tekonsha P3. Looking for correct brake controller adapter. You show 3040-P, but your photo appears to be the 3041-P because it has the extra ground wire. Does the one you recommend have this ground wire? Does it hurt to have this extra ground wire? Thanks

Expert Reply:

The Tekonsha Plug-In Wiring Adapter # 3040-P is supposed to have the additional ground strap for your 2019 Toyota Sequoia. This was something that was not always on the harness but was added some time ago as the factory wiring ground was insufficient. This will allow you to properly connect your Tekonsha Prodigy P3 Controller # 90195 to your Sequoia.

While it will look similar to the Tekonsha # 3041-P they are not interchangeable as they terminals are different.
