The white connector is easily visible in that compartment on my car. In fact it is clipped to the metal frame in the compartment. When I follow the wire with my hand, it goes up and forward (not towards the right rear light assembly). It looks just like this picture in this post (2nd picture down).

I guess I should do this by trial and error and see if it works.

Picking up a 2022 RX350 no towing package in a couple of weeks. I have looked through the trailer hitch thread and this is what I think should work for my non trailer package 2022 RX from Etrailer. Trailer Hitch Draw Tite 75540 Wiring harness 118255. Not concerned about the trailer hitch just looking for any opinions on the wiring harness for the vehicle. I installed a Toyota factory hitch and wiring harness on a 2018 Highlander with no issues and this wiring harness looks similar to that. Thanks

I just took delivery on the same RX and emailed with eTrailer and they recommended the same Draw-Tite. I’m a little concerned though because Draw-Tite does say you need to “Trim lower fascia (for model year after 2021) ”, but eTrailer said “Draw-Tite receiver may push up slightly on the rear fascia”. Does anyone know for sure?

I have 2019 Lexus RX350 without Tow Package. I installed a hitch with no problems. Now I need to have wiring harness installed. I believe I need this Tekonsha 118255 with Circuit Protected Modulite, as it was illustrated in a video on YouTube from Uhaul.
However, I can't find the white connector as illustrated in the video, which I circled in the picture below. It seems my SUV had this run up near the tail light, and had it clamped somehow. It's not visible to me, and I can touch and feel, but I can't take it apart.
I did lots of googling, but I can't find how this problem being addressed by others.
Thanks in advance.

The key to installing the hitch when your car is not oem equipped is installing the circuit protection module, just watch the uhaul install video.
What I recommend:
1. Tekonsha 118255 4-Flat Tow Harness Wiring Package with Circuit Protected ModuLite Module // this has the wiring harness for connecting the actual trailer wiring to your vehicle and the mentioned circuit protection module (without this, trailer lighting will not work properly)
2. CURT 13143 Class 3 Trailer Hitch, 2-Inch Receiver // Installs flush for an OEM look. I installed this myself with proper hand tools then went to a tire shop and had them torque it properly for $20 big ones.
3. Lexus Plug hitch plug/cap if you're fancy
I've pulled many 6' x 8' uhaul trailers with full loads no problem but when I rented a 22' rv to go up to big bear a couple summers ago, I was pushing it. When i tried hauling the trailer during the day at 110 degrees, engine temp shot right up, so I delayed the trip for next day early morning and made it at a snails pace up the mountain. (I know it sounds irresponsible and stupid as I write this but hey, it's my car and I made it.)

Not knocking your towing but rather saying - good going man! Glad you're safe. Slow and steady.
Before we bought this car, I was researching what others have towed with it, and I came across this video - figured I would share.
This is a 2010 RX:
Question: how much does that RV weigh empty? Did you have a fully packed car as well? I'll admit, I was fearful when we towed the 5'x8' uhaul trailer for the first time (loaded w/ family in the car) but after we got going, it felt fine. Temps didn't shoot up or anything and car was fine.

Modulite Module for 2022 RX450
I am guessing that the Module with part 118255 will work in my 2022 450 as well (not tow pckg)? Ready to order it today- has anyone already tried?

Installed my Draw-Tite trailer hitch last weekend on my ‘22 rx350 f-sport. Hitch #75540 (amazon, $104 on sale , ). Only had to remove the “stabilizer” or whatever that thing is and the hitch bolts right in. No mods, cutting or trimming. Fits right up to the fascia with no trimming required. Haven’t looked at the tow wiring yet as for now the hitch is only there for a bike rack or cargo basket.

Just and update to the above. I ended up having the need to tow a small trailer so had to finally get a wiring harness. I went with the Tekonsha 118255 from amazon; . Very worth it. Total plug and play, ignore the amazon page saying "this does not fit". No ground screw to drill, no fuse to install. The 4flat harness is nicely finished off in wire loom and the plug has a built in weather proof cover. Well worth the extra $10 over the Curt.
