Towing Setup Questions For A 2019 Toyota Sienna XLE AWD


Hello, As mentioned above, we have a 2019 Toyota Sienna XLE AWD and we want to set it up to be able to either carry things via the hitch or to tow a trailer. From what I’ve read on your site, the best options would be the Draw-Tite hidden hitch style #76112 or the etrailer brand hidden hitch for the more durable coating. I think for our needs, the Draw-Tite is likely better for our needs since it’s compatible with weight-distribution, if we ever need it. Would you concur? Also, can you please tell me the difference in clearance between the Draw-Tite #76112 hidden style and the similar non-hidden version of the Draw-Tite hitch #75237. I’m guessing the former is quite a bit better on clearance given the style and extra metal supports that hang down further on the two outer sides. Next, we need the wiring harness. I’ve seen the Tekonsha #118648 recommended highly. Do you feel this is a better option than the others from Curt and Hopkins both of which are more expensive? If so, can you please share a little more about why? Next, I understand that if I want to be able to have electronic brake control recommended for towing, that I need a flat 4 to 7 round converter. One that was recommended was Item # ETBC7L which works with the Curt wireless brake controller. One thing that I wasn’t clear on is whether this will work with other controllers, if I were to choose something else in the future? I may pause here, at this point, until we actually plan to do some towing. But I have a couple more questions just so that I’m clear on everything we’ll need. : Obviously, if we do want to tow with electronic brake controller, we’d need to add the controller itself. I’ve seen the Curt Wireless Bluetooth C51180 option mentioned a couple of times and it seems really cool since it doesn’t require any dashboard mods. However, would there be any other other options for a proportional controller that would work with the 4 pin to 7 pin converter discussed above, in case we wanted something a little less expensive? I just want to be sure that the converter doesn’t lock us into just one brake controller option. Lastly, is there a simple 7 pin to 4 pin flat converter? I know that probably sounds silly but since we want to go ahead and have the 4 pin to 7 pin converter installed with the wiring harness and hitch all at the same time, I realize that there might be times when we want to tow a small trailer that doesn’t have a 7 pin round wiring adapter. I seem to remember being able to get a simple plug converter that can be easily used when needed without any other wiring. Would this be possible or is there a better option if we need to ever plug a 4 pin flat trailer wiring harness into our system ending with the 4 pin to 7 pin converter? Have I missed anything that we’ll need for this setup either in the short or long term or do I have anything wrong thus far? I want to be sure I can wrap my head around all of this before diving in so that there is less potential for confusion or issues down the road. : I’ve read on your site for hours trying to be sure I learn all that I can but would prefer to hear directly from someone with your extensive experience and expertise if there’s anything I’ve missed or gotten wrong. I’d also love to hear more about the products mentioned above. I read on about air lift helper springs for the rear suspension starting at $89 on your site. I also saw that there are also such things as an optional compressor controller close to $300. Since this is optional, how do you add air to the helper springs if you don’t choose the use an optional compressor controller? I’d like to understand this, too, if possible. Do these air helper springs help protect the OE suspension springs at all or does it just help improve the ride under load. I would think both but again, I’m curious to learn from you. Lastly, we’ve recently heard of “lift-kits” available for the Sienna which gives a couple of extra inches of clearance under the vehicle. I’m not at all sure that we’ll actually invest in one but I just wanted to make sure that the planned setup above would be compatible with such a thing, should we ever want to add it. The only thing I could see being a difference is improved ground clearance but again, I’d like to hear this from you. Thanks so much in advance! Sorry this is so long but I wanted to be thorough and try to get any info and answers all in one place for simplicity. I really appreciate any help you can offer. :

I would agree that if you foresee the need to tow in the future and use a weight distribution system or just want to have the option, the Draw-Tite hidden hitch style # 76112 is the better option for you. I did contact the manufacturer on your behalf and clearance as far as distance from the bottom of the bumper to the top of the receiver is less than 1/2" for both, so no difference between them. Same story as well for the measurements out to the edge of the bumper. The only real difference is appearance with the Draw-Tite # 76112 in that it does not show the cross tube so this would be another reason for my preference over the Draw-Tite hitch # 75237.

I recommend the Tekonsha T-One # 118648. Tekonsha is known for being extremely reliable and this will work great for your vehicle.

The Curt Echo # C51180 is your only option that has the plug and play installation. The Tekonsha Prodigy P2 Trailer Brake Controller Proportional # 90885 is your best bet if you decide to forego that option. This does require the dashboard installation and is a more involved installation for sure. The # ETBC7L is the installation kit for the Curt Echo and is my recommendation. The only wiring required is to run a power line to the battery.

The # ETBC7 wiring kit would be needed for the Prodigy P2. Installation requires running wire inside the cab of vehicle and then mount to the brake controller that would be mounted in the dash. Either way you go here, you will have both a 4-way and 7-way connector at the same time so you won't need the adapters.

The Firestone Coil-Rite Air Helper Springs # F4155 are a good choice but there really is not a need unless you want additional support in the rear or if you are certain you plan to do towing. These will also help extend the life of your factory springs, especially if you do a lot of towing.

There's a lot here and I tried to simplify where possible. Included are additional resources should you have more questions.
