CURT 57672 Vehicle-Side 4-Way Flat to 7-Way RV Blade Trailer Wiring Adapter with Dual Outputs

kevin: Easy to wire, works great. One area of improvement is the mounting bracket. I’m not sure what vehicle they had in mind when they designed it, but the size, shape, and holes on the mounting bracket are insufficient. Plan to buy additional mounting adapters or craft one from a few pieces of aluminum bar.

Chris S: This 4 to 7 pin adapter does exactly what is supposed to do and is well built. The plug is sturdy, solid plastic. The bracket fits well. The wires are securely attached and high quality. I recommend this product with no reservations.

JSmith: The long body conflicted with the truck hitch frame so had to mount further to side - fortunately camper plug cable also off to one side!

Cat Fiend: Arrived quickly via an Amazon Locker. Arrived faster than if it was shipped to my business or home. Perfect sealed clamshell package. Is authentic CURT Mfg. Easy install, as easy as anything can get when you have to slide under your pickup and work looking up. Nice features like the wires already with connectors, ready to crimp. have not had a chance to tow with it yet, will update if there is a problem.
Of note: this is my 2nd replacement. My Curt Echo Bluetooth Trailer brake controller, which get's mounted into this Curt Connector, that Echo is very very tight and to remove it, I had to yank and yank and it finally came out, but with the power blade from the connector stuck in the Echo controller. I've done this twice, and both times had a pro install the new connector at a couple of hundred bucks each time. I finally decided to install myself, save 200+ bucks and it went in very simply. I've filed any corrosion off the Echo internal connectors, added some diaelectric grease and now the controller comes out of the 7-way Curt socket with no damage to either part.

Ms. Parrothead: Easy to install. Good instructions. Like that it has the round and flat connector all in one. Works great for lawnmower trailer and boat trailer. I would recommend this product

David A. Soussan: I already had an aftermarket 4 pin flat trailer connector but we were going to pull a small RV with our 2015 Lincoln MKC. Following the wiring back up to the add-on box and further to the rear power distribution fuse panel, I was able to provide power to the connector pretty easily. I was told for what we'd be pulling I didn't need trailer brakes or the backup lights so I left those not connected but did wire a good power wire to charge the batteries in the trailer. Worked like a charm! Found a video online from uhaul that outlined how to get in back and what to splice into (which were already spliced into by the other trailer hitch installer).
