Trailer Wiring Harness for a 2017 Lexus RX 350 F Sport

Question:

Just got my rx months before and I want to install a hitch in the coming weeks. The curt hitch is really good to me. But my concerns is about the wire. I dont think my car is coming with a tow package since I didnt request for it. But I do find a white plug under the bumper which can connect to the harness . I read some trends in the lexus forum, people said all the rx 350s have this plug. But having the plug doesnt mean I have a tow package because this plug wont have power. And even the plug has power, I still need a extra convertor. So my question is how I can make sure if my rx is coming with a tow package or not ?

You can have a Lexus dealer look up your VIN number for your 2017 Lexus RX 350 F Sport and that should tell them which options the vehicle has. Another option is to use a circuit tester such as # PTW2993 or a meter if you have one to test that plug you found.

Have someone sit in the vehicle and operate the brakes, left and right turn signal, and headlights while you test that plug. If it has power and if the brake lights are on the same circuits as the turn signals then you do have the tow package and won't need another converter and you can use # 118252.

If there is no power or the lights are all on separate pins then you would need another converter using # 118255 which does come with a fuse needed to activate that plug you found.
