Adapter 4 Pole to 7 Pole and 4 Pole w/Test Lamps
This is the second vehicle I have installed this adapter on. We tow a Coleman popup and another smaller trailer so we need both the 4-pin and 7-pin adapters. The test lamps are great to confirm that you have installed the wiring correctly.
The adapter was easy to install and works great. I really like the LED status indicators on the socket. I had the voltmeter out but didn't have to use it.

Adapter 4-Pole to 7-Pole and 4-Pole
Really nice trailer wiring adapter. Very easy install. Takes about 30 minutes with all the tools needed. Drill, 7/64 bit for pilot holes to mount the bracket, flat blade screwdriver and 11/32 nut driver and two #10 self tapping metal screws with locking split washers and a couple zip ties to tidy up the wiring harness.
I looked at so many options before deciding on the B&W hitch, but I have no regrets buying it. There is nothing that my car is suitable for towing that this thing can’t accommodate. I even use it on the front hitch of my mower to move trailers around the yard! Adjusts very easily and stows nicely (though on my Ford Edge it rides lower than I like when stowed).

Hopkins Multi-Tow Trailer Connector Adapter - 7-Way to 5-Wire Flat/4-Wire Flat and 12-V Power Socket
Good solid unit that I expect to last a lifetime. I purchased this unit primarily to provide a charging port for a float charger. The idea being that if I forget about it or if someone else drives my truck and is unaware that it is connected, it will easily disconnect when the vehicle is driven away.
Perfect! I use the 4 flat for my boat trailer lights and the +12v I've wired to charge the boat battery as I drive to and from where ever I'm fishing; brilliant!

Curt Trailer Connector Adapter - 4-Way to 7-Way RV and 4-Way Flat
this product was exactly what I needed and I could not obtain from a local supplier. Price was right. It arrived within a reasonable time frame, install directions were clear and the initial install was simple and I had connectivity right away. I was able today to test with the trailer attached and it all works. Thanks,
I just installed this on my 2015 Volvo XC70. I also used the Curt XC70 plug and Play for wire kit. I watch two of etrailers excellent insulation videos. Installing the hitch and both the wiring products took me around 3.5 hours. I think Curt products are great and they are reasonably priced! e-Trailer makes your DIY installations easy. You just need to take your time when removing interior panels and double check your work. I used Volvo's torque specs for the bumper parts when I installed the hitch. E-trailer doesn't stop with just hitches and wiring solutions, they have just about anything you need to load and haul overhead or behind safely. What about performance? E-trailers got you covered. If you get in a jam during the insulation, don't fret or worry, call the text at e-trailer and they'll walk you through it. I want to thank E trailer and their professional staff for helping me with my truck and auto towing and lighting solution for over 10 years now!

Curt Trailer Connector Adapter with Backup Alarm - 4-Way to 7-Way RV and 4-Way Flat
I never used it. It does not fit my motorhome. Still sitting in my garage.
Perfect fit with easy installation instructions!
