I can't help you with wiring but how about some FREE towing advice..??

There is a design flaw in your transaxle that might result in premature failure if you plan to tow something over 500-1000 lbs, and even that in hilly terrain or with a heavy cabin load in addition.

With the advent of the RX330 Lexus adopted DBW to "protect the drive train" due to the design flaw.

It is my understanding that if you have the "tow prep package" then you can just plug in the factory harness (similar to what is in your picture). If you don't have the "tow prep package" then there is some type of electronics box that has be installed in the back and this is what provides the dongle for the wiring harness.
