Video Transcript for Curt Mounting Bracket for 5-Way Flat Trailer Connector Spec 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.

All the parts were included and they fit right into my Towpower hitch. I do wish there was something a bit more robust to hold the connector in place other than the teeth on the bracket. If I really push down on the connector when attaching the trailer harness the plug recesses a bit and I need to pull it back through.

Maybe it's user error because I don't see a way to use the two unfinished screws that are included. If that's the case though, it would have been nice to include a small set of installation instructions (there are none) to clarify.

Overall though, happy with the purchase and this looks a lot better than a harness dangling by a zip-tie!

It didn't fit the lite kit I got from you.the trailer plug hook up is wrong size. But I will try and make it work

by: Eric 08/23/2019

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...

Thank you for your fast delivery

by: Michael 10/31/2018

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

by: Stephen 11/01/2019 One Year Later

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

by: Mark 05/29/2024

I would have given five stars instead of four if it would have better corrosion protection. My last one rusted out in five years.
However, it does it's intended job well and the price is reasonable.

How to Add a 5-Way Connector to a Vehicle That Only Has a 4-Way Connector
Hey Rob! To add a 5-way connector to your Sienna you'll need the Curt Trailer Connector Adapter item # C57187. The blue wire will be spliced into the reverse light circuit. The easiest place to find the reverse light circuit is the wire loom that goes from the hatch to the body of the vehicle. It can typically be found near the top. Once you find this you will need to pull out the wires and test them using a circuit tester like item # PTW2993 until you find the circuit that is only active...

Will the Curt 5-Way Mounting Bracket Work w/ the Hopkins Ergonomic 5-Way Flat?
No, I am sorry it will not Keith. The Curt Mounting Bracket for 5-Way Flat Trailer Connector item # C58303 is designed for a standard 5-flat connector like item # HM37908. The grips and the cover on item # HM47890 aren't going to fit inside the space on that bracket. Instead you'll want to use the Curt Easy Mount Bracket for 4- or 5-Way Flat Trailer Connector item # C58001. This one mounts to your hitch receiver and sandwiches the connector into place so it'll have plenty of room. What...

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 Curt T-Connector Vehicle Wiring Harness part # CU94FR 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. In order to secure the 5-way you will need both part...

Adding A 5-Flat To A 2025 Jeep Grand Cherokee
Hi Kirk! I can definitely help you get your 2025 Jeep Grand Cherokee set up with a 5-Flat! With that being said, there isn't a fully plug and play option for that, so you will need to start with the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C27BR. This is a plug an play 4-Flat, though one wire does need to be run up to the battery for needed power. From there, you will want to add on the Curt Trailer Connector Adapter - 4-Way Flat to 5-Way Flat - Vehicle...

Will Curt Easy Mount Bracket C58001 For 4 Way Connector Work On Receiver Without Lip 2026 Highlander
Hi there Richard, thanks for your business! I have a solution for you, but the Curt Easy Mount Bracket # C58001 is designed to clamp around the lip/collar at the end of a 2" receiver, so I would not recommend it for the Trailer Mate # TMT67FR since that receiver does not have that style of collar. It's possible it would still get tight enough, but I wouldn't want to guarantee it! Instead, I recommend using the Curt Mounting Bracket for 5-Way Flat Trailer Connector # C58303. This can either...

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. The no drill mount bracket extension # 18140 will hold the round tube tight and will not twist without significant force from direct impact. 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,...

Recommended 5-way Connector and Trailer Hitch Receiver For 2021 Mazda CX-9
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 Hitch And Wiring Harness For 2019 Ford Ranger To Tow Boat Trailer
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 etrailer Trailer Hitch you will need the # e63ZR which has a 900 lb tongue weight rating and 6000 lb trailer weight rating making it a perfect option for towing your boat. You will however need to confirm the towing capacity of your truck by...
