The 4 prong plug on the rear of a RX350 for trailer wiring,

Asked by Mar 20, 2017 at 05:37 PM about the 2013 Lexus RX 350 AWD

Question type: General

Drivers side rear quarter panel has a 4 prong plug for connecting to a trailer wiring harness.  My Rx 350 does not have a trailer towing package.  The fuse panel has a designated fuse and has power but no power is getting to the rear of the vehicle?  Does these vehicles require a separate wiring module for lighting, turn signals and brakes?

I have the same problem. Did you find out anything?

I have the same issue as well, have you learned anything regarding the issue?

rx 350s without tow package require a tow relay in order for the 4 pin harness to operate. 2010 to 2015 part number is 81985-wy010. The location is behind the passenger side taillight
