Ellen: Hey everyone, I'm Ellen here at etrailer.com, and we're going to be taking a quick look at the CURT Adapter 4-Way to 7-Way Blade RV wiring. So this allows you to have that 7-pole wiring in the back of your RV so you can connect to a towed vehicle or to another accessory that needs that wiring connection. So it's going to connect to our 4-pole on the RV. You do already have to have one installed. If you don't, you will be able to find some options here at etrailer.com to get that wiring in place. Then our other connections are going to be there as well.
So we can have all the functions necessary to run our supplemental braking system or diode wiring, and all that fun stuff for our flat tow.So let's take a closer look at it and make sure that this is going to be the right fit for you. The nice thing about this particular harness is that it does come with it a built-in tester. So on the side here are going to be some indicator lights. If something is happening with one of those, it'll let you know that the wiring is not connected properly. So normally you should have a signal from all those wires, and you can test everything out to make sure that it's functioning properly.
On the inside you can see we'll have our seven blade connector, that is a spring-loaded lid there to keep that secure and covered whenever we're not using it. Then on that lid there's also a little tab to hook into our 7-pole wiring so that helps to keep that in place and keep it from falling out.For our connections to our RV, again we'll have that 4-pole wiring, so it's going to give us our ground, the running lights, and then the right and left turn signal. We'll have an additional ground to make for the plug itself. Our 12 volt power wire, which is going to be the black wire. Blue will be our brake signal or our auxiliary brakes so that our brake controller or supplemental braking system.
Then the yellow wire is for our auxiliary or sometimes our backup signal.This does come with a mounting bracket, it does not come attached, you will have to put that hardware in there. It comes with the hardware to put that onto the metal bracket. So you'll have a bolt and then a flat washer lock washer and nut. It does not come however with the hardware to mount the bracket to your RV. You want to make sure that you find a nice sturdy spot for that.
You don't want to drill directly into your hitch, that can damage the integrity of your hitch. So maybe find a long bracket or something that can attach there. That's pretty much all there is to it for a look at the adapter's 4-Way to 7-Way blade RV connector with test lamps. I hope this has been helpful in deciding if this is the right one for you. Again, I'm Ellen here at etrailer.com. Thanks for watching.

This vehicle-end connector converts any 4-way flat, vehicle-end plug to a 7-blade RV connector outlet.This part installed easily and looks like to a quality part. The built in LED's allowed me to verify the installation and gave me confidence that things will be correct when I pick up the trailer.
part came on time
Thank you! Great customer service!
I use it to replace an old one whose ground wire was rusted. It fits perfectly in the same place. There is no problem in installing. Please remember to attach the thick white wire to the frame of the vehicle. The thick white wire is the real ground wire. The thin white wire is not being used. The test lamps make verifying the installation very easy (because I don't have a test wiring tool).
