Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's side rear access panel.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Video Transcript for Review of CURT Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C53VV

Hi, neighbors, Steven here with etrailer.com. Today, we're looking at our Curt T-Connector. It's a vehicle wiring harness with a 4-pole flat trailer connector on it. Now, folks, this is gonna be a custom fit application, it's gonna fit the 2021 through current year, 2024, Toyota Siennas. I wanna make sure that everyone is aware to check our fit guide anytime you're getting anything custom like this as videos can become outdated. If newer years are out and about, this may fit a newer year.

So again, etrailer homepage, top center where it says vehicle information. Enter things like year, make, and model, cab style, bed length, whatever it asks you regarding your vehicle to make sure you're getting the correct parts the first time. So getting into it, folks, this nice 4-pole flat trailer connection is gonna be installed in the cargo area of your vehicle, and it's gonna power your trailer's turn signals, taillights, those kinda things. This 4-pole connector is technically compatible with a 5, 6, or 7-pole adapter. Those are sold separately.

It's gonna connect actually pretty simple and quick. It's just one plug here, it's a custom T-fit connection. It's gonna be behind your driver's side rear access panel, and there'll be a plug that matches up with this. With the included instructions, you'll find what that looks like, or check out the videos on our website as well. Now, once that's installed, the 4-way plug does get stored in an out-of-the-way position inside your cargo area of the vehicle.

Comes with a nice dust connector that's gonna go over the top of this and fold down on top of the 4-pole flat to keep dust and debris out, which, again, in this particular vehicle, it's inside the cargo area, so you may not need this all the time, but I highly recommend it still. You got zip ties, a self tapper screw, and you got an inline fuse here, which already has the fuse installed. It's a 15 amp fuse it looks like, so I'm gonna close that back up. And then you have this guy, this is their surface mount technology they call it or SMT. It's going to be a power module, it's gonna connect directly to the battery via that plug and everything, and it's gonna ensure your vehicle's wiring matches the output needed for the trailer.

It's gonna help block back feed, any kind of that stuff, and that way, it's gonna protect your vehicle from any kind of wiring damage. You get this double-sided adhesive. You peel that off, you put that on the back of this, and you could slap it on the inside somewhere safe, out of the way. Or with the self tapper, maybe you put it through the mounting hole for the screw here and mount it that way as well. So a couple different options. Now, folks, again, this has been our look at the Curt T-Connector. Again, specifically for the 2021 through 2024 Toyota Siennas. Again, check the fit guide at etrailer.com, make sure you're getting the right parts for your vehicle. I'm Steven, thanks for your time. Thanks for watching, stay safe out there.

  • Availability of Hidden Trailer Hitch Compatible with WDH for Toyota Sienna
    The only hidden hitches for the 2022-2024 Sienna are the # EH22SR and the Draw-Tite 76928 which is on extended backorder. Neither of these can be used with weight distribution. I recommend installing the etrailer # e56RR which is compatible with a WDH. This has a matte black finish so the visible cross tube won't stand out as much and won't show dirt and dings like a glossy finish. You will also need the # C53VV for wiring.
