Video Transcript for Curt Wiring C58303 Review

Speaker 1: Today, we're gonna take a look at the Curt Mounting Bracket for the five-way flat trailer connector. Now, this sturdy steel bracket will let you mount a five-way flat trailer connector on your vehicle. It allows for attachment to the vehicle or to the trailer hitch. It is constructed of a sturdy steel, does resist corrosion with a durable black powder coat finish, and includes your mounting hardware for installing this. I did happen to pull this, an example of the five-way connector that'll fit in here, and basically, instead of having this hanging down on your vehicle, you can just push it right in, it's made size-wise. To push right in, and hold it right into place, then you can have this mounted on the back.

But that should do it for the review on the Curt Mounting Bracket for the five-way flat trailer connector.

My curt plug in wire fit perfect in curt support bracket. I used 2 sip ties to hold it in perfect position. Locks & works great

Will do. Thanks. Btw, had to shave a little rubber off the sides of a connector to fit it through the drain hole in my 2016 Highlander. Otherwise, straight forward and looks good! See attached...


Worked as needed


Great way to mount connector and protect it from damage. Wished it had a clip to keep it from pushing out when connecting.


Not a lot of options for 5-wire plugs, but this one works great.


worked good


Works as expected

Love the concept of this item.

  • How To Add a 5-Way Trailer Connector To a 2020 Hyundai Palisade
    In order to add a 5-way trailer connector to a 2020 Hyundai Palisade you will first need to start with a 4-way, the T-One Vehicle Wiring Harness part # 118784 then you can convert this to a 5-way with the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter part # 20036. The blue wire will need to be spliced into the vehicle's reverse light circuit because this is what triggers the brakes to release so the trailer can reverse.

    I would be happy to help! There is not a dedicated 5-way connector for your 2021 Mazda CX-9 Grand Touring AWD, but we can get you taken care of with something that will not be unsightly. I recommend the # 118278 which is a confirmed fit for your vehicle, and then converting it to a 5-way connector using the # C57187. To pretty it up I recommend using some electrical tape to go around the 4-way connector on the adapter and on your vehicle, and on the wiring to keep it nice and bundled....

  • Recommended Trailer Wiring Connection Mounting Bracket On 2018 Honda CR-V With Round Crossbar
    The bracket extension for your Draw-Tite Trailer Hitch round cross tube is the way to go to mount the Curt 5-way flat bracket # C58303.

Another great option for a 2 inch receiver is the Curt Easy Mount Bracket for 4- or 5-Way Flat Trailer Connector # C58001 or # C58002 for a 1-1/4 inch receiver. These mount to the collar of your receiver tube,...

    I would be happy to help! For your 2019 Ford Ranger you will need a trailer hitch receiver, a 4-way connector, and then a 4-way to 5-way adapter as a 5-way connector is the most common connector used on a boat trailer. Since you mentioned wanting a Draw-Tite Trailer Hitch you will need the # DT73GR which has an 1125 lb tongue weight rating and 7500 lb trailer weight rating making it a perfect option for towing your boat.
