4-Way and 7-Way Wiring Harnesses For a 2005 Toyota Sequoia SR5 Without Factory Tow Package  


Looking to add a trailer hitch Curt and wiring harness to a non-hitched 2005 Toyota Sequoia SR5. What do you recommend other than the Curt hitch, need recommendation on wiring harness.


Helpful Expert Reply:

As you have already found the Curt Trailer Hitch Receiver # 13440 for your 2005 Toyota Sequoia SR5 you will need to choose the wiring based on the trailer you intend to pull.

For small trailers that only require a 4-way flat connection the Upgraded Modulite Vehicle Wiring Harness Kit # 119147KIT will be the only wiring you need. This will control the lights on the trailer from your Sequoia. I recommend using the Mounting Brackets # 18144 and # C57202 to secure the connector on your Sequoia.

For larger trailer that have electric trailer brakes and use a 7-way connection you will need a few other parts. You will still need the Upgraded Modulite Vehicle Wiring Harness Kit # 119147KIT to attach to the Universal Installation Kit for Trailer Brake Controller # ETBC7. This will give you the wiring and circuit breakers needed to install a Redarc Tow-Pro Liberty Brake Controller # RED24FR, using the Pigtail # RED69FR. You can use the Mounting Bracket # C57202 to attach the 7-way connector with its included bracket.
