7 pin cable
Due to a bit of age/corrosion, I have decided to replace the 7 pin plug/cable on the trailer. As I usually do when I am about to tackle something I haven't previously dealt with, I searched the net...

Maybe the new cable was too short for his application. More contacts and breaks, more corrosion possibilities and breakdowns. I would go with one junction box.
X2!
Most likely the person in the video was not able to get a cable long enough so splicing somewhere else would be needed.
Not ideal but could work in a pinch.
As someone else mentioned, they do sell prewired/molded cables with plugs in different lengths and even different wire ga sizes. You can also buy bulk wire for 7 pin harness to customize your cable to the length you need and then add a replacement plug to that.
Much better however to get a cable long enough or even a bit longer in the first place and go back into the original junction block. Otherwise you are adding an additional point of failure with an additional splice.
Extra junctions or splices can eventually come back to bite you in the behind and that typically happens at the worst possible time..
