Most Popular Vehicle End Connector for 1979 BMW 3 Series

Installed on a 2009 328i BMW, took more work to get interior panels off/on in trunk area than the wiring. I had the electrical wiring diagrams for the car which really helped.

One year review - I installed this on a 2017 Armada. The install while straight forward did require removing some interior panels to access wiring. I have about 15,000 miles of towing a travel trailer on this device and it has worked perfectly.

After another store botched my SUV wiring installation leading to a short circuit and a need to rewire, I found this item for a great price. I wired it myself. It was simple and has worked perfectly with my LED lights and new trailer wiring. Very happy.

Installed the Hopkins muti-tow 7, 5, and 4 way flat connector this morning. I ripped the original connector that was attached to the bottom of the hitch receiver off when I was 4-wheeling into the Doll House campgrounds in the Maze District of Canyonlands a month ago. So, I cut a hole in the bumper and mounted the new Hopkins connector, cut off the old broken connector mounting bracket, and connected the factory wiring to the new Hopkins device. Hopkins product installed easily, looks great, is now out of the way, and has the flexibility of multiple trailer connectors when required. I am pleased with the product. Attached is a photo.

Exactly what we had been looking for. Now I can hook up multiple trailers with different connectors and all the electrics on each trailer works. I mounted mine directly to the receiver hitch frame. The biggest challenge for us was routing the backup wire from the taillight housing, through the body of the truck to the connector. the rest went together fairly easily. Seems to be pretty solid and looks much better than the loose pigtail connector it replaced.

Very strong wire on the connector. Finger hole access is priceless!

easy installation, I like the indicator,

The pins were too big by a little bit. Had to force the female plug into the socket

Nice product. Proper di-cast with chrome finish...not the cheapy plastic one this replaced. I prefer this to the flat-4 plug, because the flat-4 can't really be secured the the vehicle, and most of the time thay are run out the truck over the bumper. I didn't want to risk scuffing the painted bumper cover, plus I have a 3rd brake light on my trailer, which requires a dedicated brake light wire. I installed this on a 2006 WRX and a 1990 Mustang (1 trailer, 2 cars that tow it)

I used the Hopkins 3 to 2 converter to make a 6-pin round to 4-flat connector for my Winnebago View motorhome. While there are 6-4 plugs available to do this, they do not work on the Winnebago View (no brake lights). This adaptor works great.

This device was no help in connecting my five wire trailer to my four wire goldwing. I ended up having to use a number of diodes in the trailer wiring to make everything work properly. My trailer had red LEDs that were used for Brake, Turn & stop and I had to get the brake and turn function to share the same lead on the light fixture.
