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

Installed and hooked this up on the back of my old d350 just had to plug in my flat plug for lights and add my trailer brakes

Pretty good

This connector is amazing. I originally bought the Hopkins 7 blade trailer connector from my local tractor supply store. JUST the 7 blade, and it costed me $30. This is the 7 blade and 4 pin for just $14 how can you beat that? Everything is quality. Mounting is very easy and pre-drilling 2 holes is required. The only thing I have to say about this that was kind of workful was the wiring, but I cant take away a star because this thing is universal for many vehicles. I have a 2005 Tacoma and the only wires that color code matched were black, white, and blue. I had to expose the rest of the wires and match them by hooking up to a trailer and testing the blinkers and brakes to the corresponding wires. This was very easy with another person helping, it took me about 5 minutes. Overall I highly, highly recommend this product to anyone in need of a new trailer connector.

Correct part, delivered on time.

Used this to wire up a Tekonsha brake controller, etc to a 2008 Toyota Sienna. Nothing particularly exciting to note here, its exactly as pictured and described. After spending some heavy cash on a kit from a particular online trailer place for my last tow kit, I found it cheaper and less wasteful to order the parts separately.

I replaced a broken 7-pin connector with this part. I didnt need the male 4-pin connector, just clipped it off and spliced all 7 wires to the truck harness. The 4-pin and 7-pin portions are connected inside the molded plastic housing. A great way to add a 4-pin hookup for a boat or light trailer if youre starting out with just the 7-pin (the 7 to 4 adapters cost more than this part does.)

This adapter gives you a flexible solution to the 4 pin vs.7 pin trailer connection. It has BOTH connectors in one unit and the mount accommodates both of them. I have a small utility trailer that has the 4 pin connection, and a travel trailer that has the 7 pin connector. This make it simple to hook up either trailer.

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.

This product will do what is says it will do. That being said, it does not inspire confidence in heavy use situations. It does not appear very rugged. Nice that it comes with the mount, but again the mount is very thin and light and probably wont last very long. Also, the wire coloring does not match with the standard US codes. White is ground on the item, while in most cases in the US, black is the ground wire. Where was this thing made? Again, it is a good price, and a useful product, but just beware it might be very rugged or reliable. Make sure to read the enclosed documentation so that you match your wiring correctly.
