Hi,
I have a 2007 Rx 350 that I installed a tow hitch on. However I also need to install the cabling for a tow hitch light in order to legally pull a trailer. Has anyone installed this themselves? I ordered a kit from ETrailer but they don't provide specific info for my Rx. Thank you!

 

remove all the plastic bins and spare tire accessorry holder from the rear and look for a rubber grommet , you can remove that and fish your harness through there.

I would advise against towing anything without the tow package.

 

Check behind all of the plastics in the trunk. I put a hitch on my 09 rx350 so I can use a bike rack. There’s already wiring in place. Forgot which hidden compartment I found it but it was already there.

 

Do you know if your Rx came with the factory tow package? mine did not

 

got it! Do you recommend against towing without the tow package because of the radiator? I only plan on towing a trailer in town short distances

 

You found the harness?

I don’t tow anything, just a bike rack. I don’t see an issue with a small trailer around town. A friend of mine tow his 14’ boat with his 2005 rav4 for the past 2 years without an issue. Boat weighs around 600lb.

 

I wasnt able to find anything. Maybe your rx came with the factory Tow package? Does your Rx have AWD?

 

Not sure if mine came with a tow package. I don’t see any transmission cooler so I don’t think so. My RX is AWD.

 

I towed with my 07 with tow package. 4x6 uhaul trailer with bedroom furniture in it and a toolbox when I helped my mother in law move. Other times with other household furniture. Nothing i could call a heavy payload except for heavy bedroom furniture but that's prob nothing vs bricks or concrete. Did it a few times on flat nj roads extensively last year, I could definitely feel the car struggling. Gear shifts would be longer. Never anything to make me uncomfortable but I got the tranny and diff fluid changed when i was done that part of my life though!.

 

#1 - On the front bumper look into the slot under the driver's side fog light, if it has a tiny radiator set was back it has the tow package
#2 - email Lexus/Toyota America ask them to email you the build sheet, I did that with mine last year it'll tell you what options your car has. This is free
#3- on the driver's side of the radiator look at the very bottom corner, if it has two small hoses attached it has the tow package. The tow package requires a different radiator than the non tow model

 

if you input the VIN in the Lexus app, you can see that immediately.

hit “Glovebox,” then “Specs and Capabilities,” then specs.
