How To Add Both 4 and 7-Way Trailer Connection Points On a 2020 Toyota Sienna

Question

Question:

Hello, I need to install a wiring harness to pull a small trailer on my 2020 Toyota Sienna LE AWD minivan. Looking for one of the options: 1: wiring that has both 4 way and 7 way trailer wiring harness 2: only need 7-way trailer wiring harness. I already have the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2inch # 76112 installed on my van.

The Tekonsha OEM Replacement Vehicle Wiring Harness part # TK87FR is the only plug-in 7-way trailer wiring harness for a 2020 Toyota Sienna so this is what I recommend. It has a 7-way only but you can switch out the plug to the Hopkins Endurance Multi-Tow part # HM40950 for both 4 and 7-way. Don't forget the Mounting Bracket and Installation Hardware part # PK12711U so you can secure it.
