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

I havent hooked it up yet because a tester I bought shows the tail light is not working from the current adapter. I will be using this soon and believe I may have found a work around, otherwise it will fit just fine to the new trailer that I bought this for, I think the capped wires may be used for trailer braking which I dont plan on using at this time but nice to know its available.

Simple and easy way to make up for Fords Super failure in their 1999 Super Duty truck. Dont get me wrong - I LOVE my truck but what was Ford thinking producing a truck of this caliber with no RV7 trailer plug. Sure in 2001 they fixed the problem but I dont HAVE a 2001 truck. This was an excellent way to get on the road immediately to bring our new (to us - 1995 28 trailer) camper home from the seller. Some extra wire hookups and a brake controller and now my truck is a TRUCK again.

It was what it was described to be

Easy install

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.

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 7-way/4-way trailer adapter is exactly what I needed for my DIY after-market hitch install. It easily mounted on the bracket on my hitch and the wires are plenty long enough to reach existing wires and easily hide around the frame. The 7-way connector firmly holds my wire in place and makes a great connection to the trailer. I have not had any problems with the connection to the trailer as I have with older 4-way wire connectors. I highly recommend this product to either add a 7-way plug or replace a 7-way plug that still allows a 4-flat connection for non-braked trailers.

Ironically, the 4-pin plug on this which is made to go into the vehicles 4-pin plug had rubber shielding around the metal terminals to create a seal. I installed this on an 03 F150 which also had said shielding. The two wont work together, only one end is to have this shielding or boot. But fear not as the fix is easy: I just took a utility knife and cut the rubber off the plug on this Hopkins unit. It then plugged into the truck fine. Otherwise, these are not of the most robust construction. Hopkins also sells a more heavy duty adapter under the Endurance line which is of better construction. Ive used both and will opt for the Endurance in the future. The Endurance is gray in color and has a raised X on the 7-pin cover.

Bought a trailer with brakes about a year ago, but only had the 4pin trailer plug (no tow package) on my F150. Bought this piece, got it in 2 days with Amazon Prime, and installed it the same day I got it. Install took about 30 minutes (you could do it faster if youre familiar with the wiring), but overall pretty easy. 4pin plugs into the new 4pin (plug and play), splice blue wire for the actual brake controller, splice black for power, and white for ground (to metal of vehicle) -all not difficult (youtubed this video for help: http://www.youtube.com/watch?v=XWq9Fwj1D-8). Now I have braking power on my trailer (also got Curt 51110 Venturer Brake Controller and adapter for simple installation: 5min), all for almost $80 and about 45min of install time. Took trailer for a short trip and everything works great, next is 1600miles, so Ill update if something craps out. Otherwise, consider everything great.
