Adding a Trailer Wiring Harness and Brake Controller to a 2006 Toyota Sienna
Question:
Thank you for the return email. Of the two wiring harnesses you mentioned in FAQ, why might I want to pay double for the one with the battery powered lead. Is the converter really going protect my elwctroic system should it get taxed too much.. Should I be concern about the wiring over load with the cheaper one?

Trailer wiring harness # 118648 fits the 2015 to 2017 Toyota Sienna but not your 2006 model. For your 2006 Toyota Sienna the comparable trailer wiring harness is # 118304. This is not a powered harness though so if you want one that does both fit your van and require a connection to the battery you can use Hopkins harness # HM11143485.
Since the trailer you want to tow has electric brakes you will also need to install a 7-Way trailer connector, in addition to one of the 4-Ways listed above, as well as a brake controller.
To add the 7-Way and the wiring for a brake controller you will need # ETBC7. Then for a brake controller I recommend the P2 # 90885 because it is easy to set up and use and it is reliable. I have included some links below that show and explain the ETBC7 installation.
