Question:
I have a 2024 Lexus RX 350 and I am wanting to be able to tow a jet ski. So I need a flat 4 prong wiring harness to be installed on my vehicle. I have a shop that will do the work, I just need the parts, and I dont know what I would need. Can you help?

Hey Karla. To add a 4-way wiring harness to your 2024 Lexus RX 350, you'll want the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # TK92KR. This harness fits the RX 350's that do not have the factory towing package. It plugs into your Lexus's factory wiring, which is located in your rear cargo area on both the driver's side and the passenger's side.
If you do not already have a hitch, I recommend the Curt item # C29VV. If you have any additional questions feel free to throw them in the comment box below and I'll be happy to help you.

Hey Karla, how did things go with the T-One wiring harness on your Lexus RX 350? Did your shop have any trouble connecting it to the factory wiring in the cargo area? Your update could make it easier for others looking to tow with the same vehicle.
