Since you have power at your 2005 Toyota Highlander's factory connector but no power output after the converter, it is likely that the converter is bad. I recommend testing the wires on the harness before the box if you haven't already. If you have power at that location and no power at the 4-way, you will need a new harness. If you need a testing kit, # PTW2993 will work great for you.

If you do discover power on the wiring harness before the converter box, you will need a new 4-way wiring harness like the T-One Vehicle Wiring Harness for Factory Tow Package # 118248. I went ahead and attached a video of the 4-way installation to this answer.
