    Paul, could I swap out my 4 pin connector to a 7 pin connector, and add an additional wire from that 12v trickle/constant and run it back to the trailer I’m building for a power wash/soft wash trailer I’m building to power a noco battery maintainer/charger? I’d like to run some lights off the battery

    You do a great job of videos, None better, I believe. So Thanks for that, but I have a problem and I and I am sure there is plenty of others also in my predicament, want you to do a video of taking the 4 wire on the trailer and hook it to the HOPKINS 7 Pin Plug with a Pigtail and all the Colored wire dangling from it to connect to the trailers 4 wire system. I have electric brakes on my Utility Farm Trailer dual axle.I await your great Video of this as for one thing the clarity of your videos as well as the expertise you exhibit with such great confidence as you work. I appreciate that in a man doing a video or job or whatever. Thanks....I am in a bind right now and if you could slip this one in fairly quick would appreciate it.
