Question:

I need to know which wire harness I need to purchase. My HL has the tow prep package

Expert Reply:

Since your Highlander has the tow package, you'll want to use the Tekonsha # 118248 wiring harness. You'll want to use a circuit tester like # PTW2993 to probe the sockets on that connector in your photo to make sure it's active. If it isn't, make sure there's a 20A fuse installed in location # 11 in the fuse panel in the engine compartment (see provided diagram).

I've linked you to an installation video.
