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

It was what it was described to be

I have an older Ford F-150 with the 4-pin style tow connector. I was renting an RV for our family vacation that had a 7-pin cable, so in a way, this adapter helped make our vacation possible. I drilled two holes in the bumper and screwed this adapter into them (along with the ground wire), and then had to shave off some of the plastic on the 4-pin cable to get it to mate with the existing connector on the truck. The instructions were just OK. All in all, installing this took about an hour. It seems to work well, so I recommend this product for those with older trucks and newer trailers.

I like this product!

Labeled like new, but was obviously broken.

Quality

After searching for a 7 pin adapter for my 1999 Tahoe, I purchased this 4 pin flat connector wiring kit with Hopkins 41125 LiteMate Vehicle to Trailer Wiring Kit. It was straight plug and play for my truck. I will note that you need to buy self tapping screws, as they were not included in the hardware.

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.

Plugs into an existing 4-flat for lights if you have one in place, or that connector can be cut off and the wires individually spliced. The other three wires, for brakes, back-up and 12v have to be spliced. It comes with butt splices. You have to know what you’re doing. If you have a vehicle that has separate trailer light wiring and a connector underneath, like GM trucks and Suburbans, you would be much better off getting a connector made to connect to your specific brand of vehicle, and avoid splices altogether.

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.

Worked great for over a year until the round cover broke off. There arent a lot of choices with the 7 and 4 prong plug ins. I bought it again. Will be very careful. I have a different brand one on my pickup. Its 25 years old. Hasnt broken. They dont make things to last anymore.
