Today on our trailer, we're going to be installing the 7-Way Round RV Style Trailer Connector, part number A7WCB. Now to begin our installation, we'll go ahead and remove the set screw here on our 7-way connector to remove the inside. We'll then go ahead and remove the white sleeve that will be used to hold the connector in place on our 7-way wire. We'll now take our 7-way wire connector cover, slide it over our black 7-way round sheathing. We'll now go ahead and cut the sheathing off of our 7-way wire to expose the seven wires within it. We'll then strip away the insulation from each of the seven wires and connect them color for color as indicated on the 7-way plug.
Now here before we connect the last two wires on the round, we'll need to connect the yellow wire into our center post. We'll do this before we do the last two wires, just to give us a little more space to get the yellow wire in place. Now with all our wires secured into the connector, we can bring the cover back over and screw down the set screw. We'll then move to the white clamp here on the connector, and reinstall it. With that tight, our connector's on, and we're ready to hook up to our tow vehicle.
And that completes our installation of the 7-Way Round RV Style Trailer Connector, part number A7WCB.

7-Way round plug lets you connect your trailer to the 7-way round blade connector of your tow vehicle. Interlock system keeps connections in place. Over-sized finger grips for secure disconnections. Durable ABS plastic housing.Very easy to install. The labeling was perfect and easy to read for the wire connection. The only thing you need to be careful with is the 2 screws to secure the wiring into the housing. I would recommend using hand tools as they will easily strip if using a power tool. I installed a bigger screw so it would tighten again. Other than that it is a great product.
Junk. Broke very quickly. Just from normal use. Its cheap, thin plastic with a poor retaining screw.
Jenny N - 04/19/2022We have an older 5th wheel and needed to change out the connector to match up with our new tow vehicle. The connection worked out perfectly!
THIS WAS AN EASY FIX FOR THE OLD WORN OUT CONNECTOR I REPLACED. SOME OF MY LIGHTS AND TRAILER BRAKES WERE NOT WORKING. THE CULPRIT, A WORN AND CORRODED CONNECTOR. THIS IS EXACTLY WHAT IS DESCRIBED AT A GREAT PRICE!
This Connector has held up pretty good so far. I am happy I chose it. I would purchase this again.
Bill J - 11/09/2021Used this as a plug for my portable 12V air compressor to facilitate access to power, rather than clips to battery. As usual, over the past several years etrailer is my go-to store for all trailer & towing needs. Excellent variety, price and prompt service. Keep up the good work..............
RW - 03/13/2018The replacement plug worked perfectly and solved my issues.
It works, only a single connection pet plug while other have 2 per plug section. We will see how oong it will hold up
Good replacement for my broken plug
Works great
Perfect fit
Great price, very quick delivery.
Wired it in and it works. Not much more to say. Works on my buddy's 2006 F-150 and on my 2003 Dodge Neon (yeah...you heard that right) and also on my 2016 Sierra Denali.
Fit and function excellent!
The only reason I do not give you 5 stars is because your web site. When internet ordering, it should instantly state when a part is out of stock. Even nicer would be expected restocking dates. The parts received were exactly what I ordered for my electric brake conversion from surge brakes at far less expense than reparing the internally rusted surge brake system. There was a plethora of information on your web site to assist me in ordering the correct parts for the conversion. Plus there were videos to see how to complete the conversion and how parts were installed and adjusted. Customer service was excellent.
Excellent, price is even better
I USED THE E TRAILER AND POLLAK BRAND AND I WOULD GO WITH THE E TRAILER ACCOUNT OF THE CONNECTION TO HOLD TRAILER WIRES IN ON THE BACK OF THE PLUG.
I RARELY DO THESE RATINGS BUT YOUR COMPANY HAS BEEN SO INCREDIBLE IN EVERY WAY THAT I AM COMPELLED TO GIVE YOU THE HIGHEST RATING POSSIBLE ON ALL COUNTS--I WISH THERE WERE MORE LIKE YOU!
Perfect fit. Easy to use. Great product. Using this to help trickle charge a battery for the trailer winch.
For $5 I guess you get what you pay for. Already a slight crack from tightening the set screw. The color code must of been of been for an RV since its all different for my snowmobile trailer. It will work until I can find a better quality connector.
Mike L - 01/17/2019Converted my trailer into a 7 wire, with the help of this connector and etrailer's how-to videos. Easy installation and good quality.
The parts installed and worked absolutely perfectly. I had to call and get them rush shipped to our house because my wife needed the trailer and had a small window to make her trip. You guys made that happen. It was a five star situation both service and parts.
Great Job on Delivery of Perfect Parts
The 7-way trailer connector was easy to install, and works perfectly with my 2019 F250.
I know it is just a trailer connector But! The great part is Etrailer's ability to get me the part, sell it to me at a good price and deliever it on time and with good packaging. That is why I buy from Etrailer and not the other guys!
