Question:
HI! I am looking for a hitch wiring for my Lexus RX450HL and installation. I found that there is no wiring harness for my model. I believe Tekonsha has universal kit that may fit my vehicle. Please i need your advice. Thanks

Hey Kwong, thanks for reaching out!
There aren't any custom hitch or wiring options for your 2017 Lexus RX 450h L, so in order to get parts on your vehicle you'll need to have a shop fabricate the Curt Weld-On # E17 receiver to fit your vehicle, and then for wiring I recommend the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT because it draws power directly from your battery and it uses clamps instead of splices to sense when your vehicle needs to send power to the light functions back to your trailer.

Hey Kwong, how did things go with the ZCI wiring harness on your RX 450h L? Did the setup with the clamps work smoothly for your trailer lights? Your update could make it easier for others with the same vehicle.
