Trailer Wiring Harness for a 2002 Toyota Sequoia without Factory Tow Package

Question:

Do you have the trailer wiring for a 2002 Toytota sequoia without the factory tow package? I cant find that wiring anywhere. Many firms offer the hitch, but none offer the wiring. Please help. Thanks

It is possible that all 2002 Toyota Sequoia models were pre-wired for a trailer connector. You can look to see if yours has the factory plug to install a harness such as # C55246. It will be located on the driver's side plugged into a dummy plug behind the rear bumper. I included a picture that should help identify it.

If that plug is not present on your Sequoia or it does not have any power then you can hardwire in a 4-Way flat trailer connector. I recommend ZCI harness # 119250KIT because with it you will not have to splice into the vehicle wiring for installation.
