MICTUNINGHeavy Duty 7 Way Plug Inline Trailer Cord with 7 Gang Junction Box 8 Feet, Weatherproof

MICTUNING Heavy Duty 7-Way Plug Inline – High Quality BuildThis plug is very nice and built to last. The construction feels solid, with durable materials and a precise fit that ensures reliable connections. MICTUNING delivers a high-quality product here—perfect for heavy-duty towing needs at a fair price.

Be aware this is wired/color coded for US travel trailer/RV. If you are using a utility trailer you will have to ignore the color code and use your wiring diagram. That being said, the cord feels heavy duty and decent, the box feels fairly cheaply made and is a little large, however that extra space will come in handy if you want to add anything! For the price; worth it 100%.I took the initiative to silicone the screw holes when attaching to the trailer frame to avoid potential leakage and rust. All in all it is a pretty simple set up; you just need your wire connector of choice and I’d suggest a deep socket set as the dividers between the posts restrict easy access. If you don’t need to figure out a different wiring configuration you should be up and running in 20 min or so! (definitely not an electrician here so I have faith in you! 😉)Here is a pic of work in progress. Even with adjusting the length of the wires etc I was ready to pull, box attached and fully tested in 30 minutes. That includes replacing a fuse in the tow vehicle - (don’t worry, it was out before I started messing with the wiring). For the price and ease of installation I’d definitely buy again.

Actually impressed with the quality for the price. Cord is nice and flexible, length is as advertised. Junction box is built well. Only issue I have is the wire colors don't match function with standard wiring here in America. They do include a nicely done diagram so it's easy to see what your working with.

Lots of reviews talking about incorrect writing, I can't really speak to that as I don't know what they received. I can tell you that on the one I received the color code matched the documents, and also matched the existing color codes on our travel trailer.I didn't have a terminal block on the trailer to start with, so my installation took quite a while. Make sure you have all the ring terminals you need before starting! During the install I really appreciated that they had color coded the terminal posts, that helped tremendously. Also really liked the spare plugs they included for the various openings, it gave a lot of flexibility to the install.Can't really say if it will be waterproof, but it is replacing a conduit box that was wide open, so it should be better! I don't have a lot of faith in waterproof boxes as I feel it is easy for water to get in and become trapped actually making it worse. I added a 1/8" hole at the bottom of the trailing edge to help with equalization and to drain anything that may accumulate.Overall very happy with the quality, will definitely buy again if I need a new plug/cord in the future.

Very easy to install, I wish I would have discovered this sooner. Makes wire connections on a trailer bullet proof. Its better than they describe and so neat and clean. I have bought other Mictunning products and always found them to be better than they advertise. HIGHLY RECOMMEND

Really well build. Heavy duty wire insulation. Coded well. Length good.

Great wiring break-out box. Significantly cleaned up wiring on a marine trailer with an electric over hydraulic setup. This makes troubleshooting any issues from truck to breakout to trailer a lot simpler. Works great!

I let’s start with the important concern most will have regarding the quality.This feels great in hand, heavy duty, and UV quality sheathing to protect the wiring. As a former Master Technician and Engineer the past 30 years I can say without a doubt this is a quality product.This doesn’t come with full instructions, but I do.1.) most of you will want an 8ft or shorter harness, and the box will be mounted up front.2.) You may need to reuse your existing 4 wire for lights and add a duplex wire for the brakes, or you’ll need 6 wires approx 25ft long for a 17’ flat trailer.3.) If starting with existing 4 wire than the Green is for the left turn signal and Yellow is for the right.4.) The white wire is your ground and the brown wire is for your running lights.5.) Unless you run backup lights or a 12v feature (center wire) you will only use 6 of the 7 wires.6.) The color coding for the harness is slightly different than a 4 wire so you’ll connect the above colors according to the diagram provided.7.) when wiring the trailer brakes you will connect one wire to white/black and the other wires to blue. So for a tandem axle you’ll have 8 wires going into 2. You probably want to run these in series and up one side of the trailer chassis.8.) The white wire Is connected to chassis ground and the blue wire connects to the green In the box which is blue inside the vehicle to your PBC/TBC. Why these colors are not universal through idk. Might even vary on your application.Nothing complicated here. The worse part is getting on your back to wire underside of trailer if needed.Great product, Good Luck.
