The tow vehicle is a 2018 Toyota 4Runner. According to the owners manual there is a service connector under the dash for towing brake connector.

Do we know anyone who can install one on the OBX?

Has anyone installed one themselves and this is a DYI project? Car

Because of the importance of braking towing anything, I would recommend that you go to a Toyota dealer and have it installed professionly. It will be a bit expensive, but it will be done correctly.
I towed a 2500 pound boat and trailer with a 1999 Toyota, and not have any problems towing, but stopping took longer than I felt comfortable with.
I had hydraulic brakes that were mounted to the trailer tongue.
How much will you be towing?
Gas milage is the problem with towing, the 1999 Toyota had a 18 gallon tank.

If installation is "plug and play" it is DYI doable> If you have to splice into the wiring harness, the degree of difficulty goes Up! You might try google/you tube> For local shops, suggest Pugh's in Nags Head or Soundside in Pt Harbor! Good Luck!

Good advice above.

I installed one on my '06 F150. Plug and play, all I had to connect was a ground. If yours is not plug and play, and you by some chance you splice into a sensor or computer circuit, big problems.

I've towed my 3,200 lb boat which has no brakes installed on the trailer with no stopping issues. The 4Runners max tow rating is 5,000 lbs. We were going to buy a travel trailer which weighed 4,000 lbs dry. The RV dealer tells me the unit we wanted was sold. So the pressure is off. You snooze you loose. The RV market is just as hot as the housing market is right now.

Thanks to all who responded to my post.

If you ever get a new boat trailer get brakes on it. Simple hydraulic surge disk brakes are fine. I had them on my 20ft Whaler which came in around 3500lbs, believe me its makes a difference

I was happy to see this trailer had no brakes when I bought it. The boat I owned before this one had surge drum brakes on the trailer. The trailer had a PITA freshwater connection to flush the brakes. I don't know how many saltwater launches it took before the brakes became inoperable - I suspect not many. I replaced those with disc brakes which were still working when I sold the boat.

Yea, drum brakes suck on a boat trailer. I had Kodiak stainless steel disc brakes on mine, they were awesome!

I have a 2016 4Runner and tow a boat and a small trailer. If you read the towing section in the manual of any new vehicle you will see two significant numbers. For the current 4Runner it's 5,000 pounds max, but only 1655 pounds for unbraked trailers.

" These models meet the tow-vehicle trailering requirement of SAE International per SAE J2807."

Page 197 if you would like to read it yourself. www.toyota.com/t3Portal/document/om-s/OM35B54U/pdf/OM35B54U.pdf

The new SAE J2807 towing standards consider braking among other things. Prior to J2807 manufacturers pretty much made up towing numbers out of thin air.

Yeah, I know little weak cars have pulled big bad boats. I'm 70 and have seen it, but it doesn't make it safe. Pulling isn't stopping.

Seems like if something automotive related is even remotely DIYable, someone has made a YouTube video on it. Go search and see what you find.

Thanks to all who took the time to respond to my request for info. After much thought the 4Runner would have been at its limit for the 22' trailer we had selected as a compromise to match the 4Runner. Besides its use for traveling another reason for buying the trailer was as a bugout vehicle if a cat 3-4-5 hurricane were to track this way. So we bought another tow vehicle which allowed us to buy a slightly larger trailer 27' with a 7,000 GVWR which will let us haul 2,000 lbs of irreplaceables with us should the big one be forecast for OBX.

Thanks again!
