Troubleshooting Installation of Curt T-Connector Vehicle Wiring Harness on 2012 Lexus RX 350
Updated 02/09/2015 | Published 02/07/2015 >
Question:
Plugged this into connector behind drivers side bumper just like instructional video...Curt Custom Fit Vehicle Wiring for the 2012 RX 350 by Lexus. The fuse box has a 30amp fuse in the towing slot that checks out. One of two possibilities...there is no power at the connector under the bumper or the issue is with the 4 prong wiring connector this is unlikely as it was new from you guys. What am I missing? Thanks for your help.

Expert Reply:
One possibility is that your 2012 Lexus RX 350 may not be equipped with an active tow package. The plug may be there but the necessary connections may be missing. I recommend checking with your local Lexus dealer to determine what is needed to activate the towing package. Some vehicles will need to be reprogrammed at a dealership to allow this wiring harness to work.
