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

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 T'd 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 product's installation. It all works like a charm.

Works great and a lot cheaper the the parts store

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 wasn't 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."

We have a 2024 Ford Ranger. The truck came with a standard 4 pin connector. My boat uses a 7 pin blade connector. Ford does not have a 7 pin connector option for this truck. This worked perfectly. I don’t need the 12 volt power, backup lights or the trailer brakes. This was easy to install and the bracket fit my trailer hitch without any drilling. The only drilling I did was to ground to the trailer hitch. Very happy with this product.

Just replaced my hold harness with this new one. love how this one does come with an attachment to upgrade from a 4 prong to a 7 prong with electric breaking and what not. Here are some good and bad things to keep in mind. Pros: - comes with the right stuff to install the wiring harness - has all features that are useful in the wiring harness - everything works according to the tests that this harness went through without any issues - does come with instructions on how to wire in the harness -this product came with the mounting bracket which is a plus Cons: - when putting the bracket on, you have to bolt it on a flat survace. It was mounted on a town hitch bar, but will hold. Not a firm fit. Can't fully bolt down as the bolts are too small to go through 3 inches of steel. - The ground is white instead of black. To mount the ground, you have to find a place on your vehicle to ground it at. I had to strip the wired to clamp in the wire to the old harness. - had to strip the wires for the adapter part to hook up, but that was expected. - on the 4 prong adapter, at least have the ground put in there so we don't have to bolt it to the vehicle just in case you don't want to drill and mess up the frame and create rust on the vehicle in the long run. Overall, I'm satisfied with this wiring harness. The old one I had to strip out barely gave power to the power breaks on the trailer, the reverse light on my old harness didn't work and the only thing that worked really well on my old harness was the parking lights. Now, the good thing about this product is that you have the option to use the mounting bracket if you want to use that, or if you have a truck like a silverado, tahoe, ford truck, toyota truck and what ever truck that you have, you can drill one 3 inch hole to fit all the wires through and the base to fit through, you can drill 4 holes where the face of the harness can mount in place and bolt the harness in. Simple if you have the tools. If you don't have the tools, you can always go to a shop or to go these repair places, they will more than willing to help you install this harness. I give this product a 9 out of 10, because of some issues, but overall, great product to get.

I had to return one of the off brand cheaper connectors. The contacts were so thick they had very little spring in them. They were also too thick. I had to crimp them. Intermittent connections resulted. Returned it. The Hopkins contacts are thinner metal allowing them to move more freely to accommodate different plug geometry. They required a little crimping to fit my plug.

Just what i was looking for . Perfect

A great trailer connector! Well made and easy to install. The backof the unit is sealed with epoxy to keep moisture from the connections. The first unit I ordered was missing the adaptor bracket and the install bolts. Looks like the package was broken and the parts were missing. However, Amazon quickly sent a replacement unit and I have had it installed - works great. Would certainly order from this vendor again and the Amazon "no questions asked return policy" makes it easy to correct any errors in orders.

El conector esta bien hecho y funciona bien

Exelente

Nice product. Both the four wire and seven wire sockest in one setup. Instructions are well written and easy to follow for installation.
