Question:

Good morning. I have a 2019 Lexus RX350L. Trying to install the Curt C56217 trailer light harness. I found the 10 pin connector, but the 4 pin is no where to be found. I have most of the rear end interior removed. I read a couple of the QandAs asking the same question but did not see an answer besides keep looking. This is a no tow package Lexus. Thanks

Hey Mark, thanks for the details!

The Curt T-Connector # C56217 is actually designed for a Toyota Highlander or a newer model RX350 L which is one reason you're struggling to find the right connector on your 2019 Lexus RX350 L.

Since your Lexus doesn't have the tow package the only Curt 4-Way kit that works for your application is the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236. This splices into your OEM wiring and then is powered directly by the battery on your vehicle. It isn't as nice as a if your vehicle had a tow package but it's the only option you have for your setup since you don't have the tow package.
