How Does the Tow Ready Trailer Wiring Harness Install on a Lexus GS350 2010
Published 11/11/2014 >
Question:
How do you connect to the LED tail light module on the 2010 GS 350? There is a bundle of wires and a module on the LED. Looks nothing like normal tail light and brake light wiring.

To install the Wiring # C59496 on your 2010 Lexus GS 350 you will need to test the wires of the taillight harness with the included circuit tester you have found to determine the functions of all of them and then wire the # C59496 to the appropriate wires as the instructions and diagram I attached indicate.
I wish I had more specific instructions but we haven't had the chance to install this harness on a vehicle like yours so I can't give you more specific instructions than that.
To get an idea on how this kit should be wired check out the install video I attached that shows a typical installation on a similar vehicle.
