Video of Curt Trailer Connector Adapter - 4-Way to 7-Way RV and 4-Way Flat
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we're taking a look at the Curt 4-pole to 7- and 4-pole adapter. Now this unit adapts a standard 4-way flat connector on your vehicle, to both a 7-way RV, and a 4-way flat connector. So this gives you the convenience of having both connector styles available at the back of your vehicle when you tow a trailer. This is really handy if you're towing different trailers, like you're towing maybe a trailer that just uses a 4-way and then you're switching over to towing a trailer that has a 7-way. This is really nice because now you have both options available at the back of your vehicle.I do want to point out that each connector has a really nice cover that goes over, and keeps the connector clean when they're not in use. And right here's your 4-way.
And then right here is your 7-way. That's a spring loaded lid. Internally, it's got like a rubber gaskets and that creates a nice tight seal when it's not in used. Or excuse me, when it's not in use, and keeps dirt, grime and moisture away from those connection points. The wiring on the back, this is a split loom design, keeps the wires contained and well protected.
And it also comes with hardware, and a metal mounting bracket to secure the wiring connectors to the vehicle or directly to the trailer hitch. Now, your installation is pretty straightforward. This 4-way right, here connects to the 4-way on your vehicle. And then you have four more wires that you need to connect. And then really you're done.Already on the end of each wire is the appropriate connector.
So on these three we have butt connectors. Yellow wire is for auxiliary or backup lights, blue wire is for electric brakes, black wire's for positive power, and then the white wire with the ring terminal on it, that's your ground wire. And that's going to do it for today's look at the Curt 4-pole to 7- and 4-pole adapter.
