Wiring Harness for a 2003 Toyota Highlander

Expert Reply:

The wiring harness you referred to, product number 118248, will not fit your vehicle. You will need either wiring harness part number 118413 or 33425 for your 2003 Toyota Highlander. If your vehicle has the tow package, please use item number 118245. This is the connector which plugs into the white plug you found. There are instruction sheets for each of the parts listed on their product page.

For your convenience, I have attached links to all of the items I referred to. I have also attached the video you previously watched in the event you would like to see it again.
