Finding 10 Pin Connector on 2018 Lexus RX 450h L to Install Trailer Wiring

Question

Question:

I have a 2018 Lexus Rx 450HL and I cant locate the 10 pin plug. Do you have photos or a more detailed diagram of its location please? BTW your tow hitch 13394 is a confirmed fit to my car. Thanks

Finding the 10-pin connector to install the Tekonsha trailer wiring harness part # 118525 that you mentioned on a 2018 Lexus RX 450h L is sometimes a bit challenging but we've had some customers come back and give us tips on where to find it.

One customer said:

"It is tucked up under the rear deck plate under the passenger taillight side. I used a mirror and flashlight to find it but realized that one I knew where it was I could feel it and pull it down just enough to plug the converter box into."

I also attached a picture of the install instructions that point out where the connector is too.

That description was part of a submitted customer review on the Tekonsha Harness # 118255 for your Lexus 450h. If you take a look at the product page (linked below) and click on the "Reviews" tab there are a few more that try to explain the plug location and some include pictures. This should hopefully help but if not let me know and we will go from there!

@PaulS on my 2018 RX 350L I found 10-pin connector on the DRIVER side of the quarter panel. With blank male connector attached. In trunk area(Driver Side). 1- Remove small cover piece. 2- Remove stored cargo cover. 3- Pull up/out plastic spacer from quarter panel. I'm sure that while hitch is different for L models, wiring is not. Sadly I can't attach my pictures in reply. Tested and found LEFT TURN, RIGHT TURN, BRAKES, TAIL also GROUND and constant BATTERY + but they are using very small wires with small amperage so Tekonsha 118225 will take care of that. The only thing I wasn't able to find is a 4-pin grey connector to attach a trailer harness. I'm thinking to splice trailer harnes into Tekonsha 118255.

Though the best way to verify 100 percent if your 2012 Lexus RX 350 is to place a quick call to your Lexus dealer with your VIN, you can also look under the bumper to the left (driver's side) and see if you have a panel that can be removed where…

Answer 9

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…
