Hello, everybody, Clinton here at etrailer.com. Here at etrailer we install, test and review a lot of different products to help you as a customer make a more educated decision before your purchase. Today we're gonna be working on the 2021 Ram ProMaster 3500. We're gonna be taking a look at, and I'll be walking you through how to install the Tekonsha OEM replacement seven way wiring made for your brake controllers. This is what our seven way is gonna look like installed. You're gonna see the plug here.

We did have to add some bracketing but it looks pretty nice and clean. I really like how it turned out. This is gonna allow us to hook up to our trailers with a seven way. And you can even use it with a four way adapter, if you do tow a smaller trailer. So this is gonna allow us to get all those necessary lighting functions and other functions back to our trailer.

So if you're looking at wiring for your ProMaster chances are your ProMaster didn't come with any trailer wiring. This kit is gonna be awesome if your ProMaster doesn't have anything. All we're gonna do is take our plug and play harness, plug it into our taillights at our seven way back here and run some wires up to our brake controller. So it is pretty nice and easy to get installed. Definitely a no-brainer.

So looking a little bit closer into our seven way our lid is gonna be nice and sprung. So that's gonna stay nice and closed whenever nothing's plugged into it. And on the inside of our plug here we do have a really nice gasket material that's gonna help keep this sealed from the elements. The only visible part, other than our seven-way, is gonna be this a little bit of our harness we're gonna see down here. Probably the best thing about this kit is that it is gonna work with Tekonsha brake controllers.

Whether you already have one or you're wanting to get a new one all you have to do is purchase this seven way wiring and then you can choose whichever brake controller is gonna work best for your application. Our amperage for our stop and turn circuit is gonna be 4.2 amps per circuit. And for our taillights we are gonna get 7.5 amps per circuit. Now, in terms of getting this installed everything is gonna be included and it's all plug and play minus a few wiring connections we do have to make up at the battery. With that being said I'll go ahead and walk you through how to get it installed now. To start our installation we're gonna come to the back of our ProMaster. We're gonna open up our doors all the way. There's gonna be these black vent covers here on the back. We are gonna just grab our Phillips head screwdriver. We're just gonna take out all these screws. On this last one you wanna make sure to hold the cover so it doesn't fall down. Get that last screw out and you just take our vent out and set it off to the side. We'll repeat this same process on the passenger side. We now wanna grab our wiring harness. We wanna grab the side with the yellow wire. We're gonna reach into this access hole here. We're gonna see the plug for our taillight. That's kind of hard to see with my hand in there, but it's located right here. There's gonna be a tab rim to push down on the top. Might be able to get your other hand on the other side. Kind of have to push down on that tab and pull out on the plug. Just like so. Now we can grab our wiring harness. We're just gonna plug that into there. I'll take this side and plug it back into our taillight. You wanna be careful not to get other wires pinched in that connector. Just push that till you hear a click. Give it a little tug and make sure it's secure and we can tuck our wiring back into the vent and run our wiring over to the passenger side. We just took a pull wire, kind of ran it up in this top corner, down to here. We taped our plugs to that. We're just gonna pull this up and through this opening up here. Now for our pull wire, we're using an airline tube but you can use a string or a coat hanger. Really anything you have available at home. You just kind of wanna pull this all the way through. Make sure to get all these tangles out of our wiring down here. Just like so. We're just running our wiring up along this top channel. There is quite a bit of room so you can kind of feed it through there or use your pull wire. Really whatever you wanna do. So like I said, we're gonna pull that up through that channel
