Hopkins Wiring - Wiring Adapters - 37185 Review


Today, we're going to take a look at the Hopkins 4-way to a 7-way and 4-way adapter. Now this adapter will convert from your 4-way wiring on your vehicle to give you this 7-way round plug and the 4-way flat wiring for your trailer side. Aside from your three main lighting functions that you'll get with the 4-way you have, this will add additional wire leads for electric brakes, 12 volt power and accessory wiring.The wire functions: the white wire, these actual wires here, that you'll get, will be a white wire and that will have an eyelid on it, that's for a ground. The blue wire right here, the blue wire with the connector on it, that's the output wire on your brake for your brake controller. The black one with the connector, that's for your 12 volt power supply. You connect this to the battery with a fuse or a circuit breaker.

And then the purple wire is an auxiliary wire for extra 12 volt power, reverse lights, a reverse lockout for trailer brakes. Now the purple wire, if you don't need it, you could just bundle that up and tape it up and move it out of the way.Basically, you can see the two longest wires are the purple and the white wire. They are about 36 inches long. Now it does include the mounting bracket and the mounting hardware to install this. A few specs on this: the connector itself, you can see, there's your 7-way and right alongside of it with a cap on it, if you pop it off, there's your 4-way.

So what you end up doing is once you plug this into the 4-way that's on your vehicle, and then you make your wiring connections, you'll have this at the back of your vehicle to use as a 7-way or a standard 4-way.The mounting bracket we mentioned does come with it. The mounting bracket, you could just slide, actually what we can do, it's got a little cut up there, so you can actually slide it over the wires, just like that. And then line it up with the holes, and that'll give you a mounting bracket to attach that to your vehicle.Now, the connector itself, few measurements, it's going to be three inches by three inches. And the mounting holes, the four mounting holes there, they'll Mount onto the four holes right here. The distance between those, is going to be center to center, two and a quarter inches horizontally, and vertically is going to be right at one and a half inches.But that should do it for the review on the Hopkins 4-way to 7-way and 4-way adaptor..
