Hopkins Towing Solutions 47185 Multi-Tow 4 Flat to 7 Blade and 4 Flat Adapter

I like this product!

This product does not fit the Curt #58140 7 pole trailer plug. The blades on this Hopkins adapter are too wide. Theyre wider than the blades on my 7 pole Chrysler wiring harness on my Dodge Magnum. Guessing this is a little gotcha thing where you need to have Hopkins adapters on both sides, car and trailer. The Curt #58140 7 pole trailer plug fits my Dodge Magnum with factory Chryslter 7 pole wiring kit fine. Update: After tweaking the blades with a screw driver and also tweaking the slots with a box opener the two pieces now fit together. Seems to me this is a quality consistency issue with the Hopkins harness as two of the blades were apparently too close together.

Its all good, but I do have to hold onto the back of this plug when plugging in a trailer, or Ill bend the bracket back. The plug itself seems to work fine.

My installation was a little different than the normal hookup since I wanted to do four things: 1) tow a small trailer w/o brakes, 2) be able to tow a trailer with brakes using a brake controller, 3) provide power to operate a macerater pump for transferring black water, and 4) provide power to operate a power lift to help load and unload the back of the minivan. Therefore, I needed a little heavier wire to the back of the minivan, but otherwise the hookup was the same. The only thing I did differently than suggested in the package was to mount the plugs on the bumper rather than on the hitch - that was a mistake, since the angle bracket has taken some damage that it would not have experienced had it been attached to the hitch. My requirements 1) and 2) were very well taken care of by the adapter package. I run a separate black wire for ground rather than use the frame of the vehicle and, like I said, due to my load requirements, I needed heavier wire. I used the black wire from the adapter as my blue wire for the electric brake support. Unfortunately, my macerater pump uses the center wire (the one marked backup lights - purple) as an auxiliary power. If I get time, I will switch that to use the black wire (aux) which seems to be more suitable, but for now that is is how it is. The heaviest user of power is the power lift. It uses 30 amps of 12 vdc, so the wires (red for positive and black for negative battery were run to it first and then Td to the other operations (one for the power brakes (2) and one for the macerater (3). Since the lift does not operate during travel and would not be in use while the macerater is running, the power is shared among them as well as the lights for the trailers (both 1) and 2) ). I had installed the standard 4-wire small trailer package which is a prerequisite for this products installation. It all works like a charm.

I returned it. It was delivered to late to use. I bought one in time from Autozone for the same price when I needed to install it.

My Explorer came with the standard 4 flat wire attachment. However, all wires necessary to complete the 7 pin connector are pulled right under the right rear tail light. I was able to tap into 2 of the additional 3 wires needed at this location. NOTE: I also put on a 2 receiver which required the removal of the rear bumper. This greatly simplified access to these wires, which terminate into a junction/connector. Even though Ford provides all the connections, the blue wire for the trailer controller appeared to be only 14-16AWG (unmarked) although it is fused for 30A. Since multiple internet sources recommended 12AWG minimum, I chose not to use the blue wire provided but to run a separate 12AWG line up to the battery and fuse it for 40A (circuit breaker actually). I actually ran a duplex (2wire) cable just in case. The two that I deemed useable were the orange (B+, aux power) which I soldered to the Black wire from the 7 pin; it(along with RT and LT) are fused at 40A which should be sufficient. I also used the Black w/green stripe (Reverse, BU) which I soldered to the Purple wire from the 7 pin. It is fused for 20A so shouldnt be any problems there either. I really like the way the manufacturer sealed this item, and maintaining the option of using either 4 or 7 pins is really nice.

Used it to add a 7 pin connection to 2008 Ford Expedition that came w/ the 4 pin connection. Mine had electric brake pre-wired, but no power line (black). I was able to make holes on the 4 pin connector holder and attach this adapter using nut/bolt. The wires behind the 7 pin connection touch the spare tire a bit, but I was able to install everything w/o much trouble. Looks professional, and so far no issues connecting/hauling a travel trailer.

Pretty good quality! It is great for the typical install, where you tow every-so-often... For professional use (plugging and unplugging daily) it would work okay for a decent amount of time but I worry that eventually the 4 screws holding the socket to the metal bracket would begin loosening, the plastic the socket is molded from is good not great. I like the layout of the receptacles. The metal bracket could stand to be a tad thicker, but it is good enough. The wires are generously sized, and I like the look of it on the vehicle. Would definitely recommend.

The product is as described, easy to install and does the job. The mounting bracket it comes with is garbage and its surprising someone thought it would be acceptable to ship the product with it.

What arrived was exactly what I ordered. There is quite a price range on similar product and I went to the center as this is for my 1999 Dodge Durango that I use only to launch my boat. What I got was impressive for the price. Everything for a complete install was included (bracket, unit, wiring, screws, etc.) and the quality is good. I wasnt expecting the leads to be sealed (wax like substance to fight water/corrosion) and this is a bonus for guys like me (again, the Dodge stays at the lake snapped to the boat and is used to launch/retrieve the boat). Also, the leads at the other end (where the wiring connects to the tow vehicle) came pre-assembled with butt connectors already attached. Not only do you not have to supply the connectors to install (I know, not a huge expense but just to call it out), but what a snap to connect to your vehicle. Just put your tow vehicle wires in and crimp. Nice! The wiring is a quality grade and the bracket is sturdy. If you are price shopping and you choose this one, expect to get more than you paid for relatively speaking.
