Hello neighbors. It's Brad here at etrailer. And today we're taking a look at the cut seven to four and five pole adapter. So as the name implies you are able to adapt a factory seven way to a four and five pole. And that's really nice because a lot of vehicles will have the factory seven way on there but maybe not the four pole. So if you look came to hook up to a trailer and realize that they have a four or five pole, you might be out of luck or have to run additional wire to permanently mount it.
Well, that's where this comes into play. So that's gonna allow you to be able to have your seven way, your four pole, as well as your five pole just with plugging into the factory seven lane. Now, sometimes your towing vehicle will not recognize the LED lamps on your trailer. And that's where this is great too as plugging that in is gonna allow this to send that signal to your vehicle making sure that your lights are actually working with your signals. So like our neighbor here they have a trailer with a four pole but they got a new vehicle that has a seven way.
So instead of having to run all new wiring for it you can simply plug this into the factory seven way. You can take your four pole and plug it in or if you have the same vehicle but you're towing a different trailer. This gives you that same ability. So having this is going to allow you to hook up electrically to those trailers. So now let's go ahead and test it.
So first I'm gonna start with my running lights. Next I'm gonna do my left turn signal, my right turn signal. And then finally my brakes. Now this neighbor also toes, a boat trailer. So having the five pole is gonna be really nice for the surge lockout as well as reverse light.
Now, for some of your foreign vehicles or high end vehicles that have LED taillights sometimes they don't have enough power to power the trailer lights. Well, this is gonna help with that. Allowing that to give it enough juice to be able to still retain your lights on the trailer. Something that's really nice about this is the size and that if you normally tow a seven pole you can simply swap this in whenever you're picking up a different trailer and need to hook up or really you can use this to hook up to any trailer. You have that ability and you can keep this in your glove compartment until you need it. And that was a look at the cur seven, two, four and five way adapter..
