No Power To Trailer Connector After Installing On 2016 Lexus RX 350

Question

Question:

I ordered the Curt receiver C13272 and the wiring harness 56083 for my 2016 Lexus RX 350 and installed them with ease. Im not sure if my car has a factory tow package couldnt find it listed on my sticker but it did have the plug-in for the wiring harness connector. My problem is I have no power to the connectors. I read where Danny thinks someone elses problem, is that it may be missing a fuse or relay. My fuse box is located under the hood. Can anyone provide me with more information on the exact fuse location in the box or relay? I really would hate to take it to the dealer at this point. Thanks

I called my contact at Curt and asked about the installation of the wiring harness, part # 56083 on your RX 350. First you can call the dealership with the VIN and ask if it has a tow package. If so ask them where the fuses or relays may be. I did some research and was unable to find the relay or fuse location for towing.

PTW2993. Turn on the headlights and use the turn signals to make sure you are getting a signal.

If you do not show any power on that port, chances are the vehicle will need to be taken to the dealership and have the computer flashed to turn on the towing package. You can also ask the dealership if additional parts must be purchased to get the towing package to work on your vehicle.

There is an option that would let you avoid all of the other things mentioned and may save you trips to the dealer. You can install the ZCI Circuit Protected Vehicle Wiring Harness, part # 119250KIT. This simply clamps around the wires you have on your vehicle and you attach the white ground wire to a clean bare metal surface and run the black hot lead wire to the positive battery post.

Answer 5

Not necessarily. If your 2015 Lexus RX 350 came with the tow package then you just need the T-One #118252, but if it doesn't have the tow package then you need the T-One #118255 with the converter. The tow battery fuse slot would only be used if…

Since you are not getting the 12V power when your truck is running, you most likely don't have a fuse issue as you stated their isn't a specified fuse or relay in the owners manual. The issue is that your truck is computerized even at the…

First, the trailer wiring harness #56083 is only a fit if your 2015 Lexus RX 350 came with the factory tow package. If it did not then that could be why it isn't working. Or, if it does have the factory tow package, it could be a missing fuse or…

Answer 9

I'm assuming you have a 2013 Lexus RX350. Did the #56083 wiring harness ever work, or did it work for awhile and then stop? From my research, the connector should work once plugged into the factory towing connector under the vehicle, unless your…
