Recommended Vehicle to Trailer Battery Charger for Trailer Battery
Question:
Do I need to purchase the 6ga wire separately? The orange and black wire and plugs from the video? Or would it simply be wired to the orange wire in the 7 pole junction box?

Without hesitation, I recommend using a 7-way trailer connector and using the 12V charge line you find at the 1 o'clock position to run to a battery charger and then your trailer battery. Most charge lines only take whatever amperage is not being used by the vehicle and sends it to the trailer battery providing a maintenance charge. Your trailer clearance lights will run without issue using either plug and drawing power from your vehicle, so the 7-way will serve you well for that function without any changes. I've attached a wiring diagram to assist.
I recommend using the Redarc BCDC # 331-BCDC1225D to give you a 25 amp battery charge and maintainer that will also allow you to add solar if you so desire. This will allow you to run whatever camping appliances you desire as you travel. This is for 75 amp-hours - 200 amp-hour batteries. If your trailer battery is over 200 amp-hours then you will want to upgrade to the 40 amp # 331-BCDC1240D. You will also want to use the inline fuse kit # 331-FK40. This will give you the go anywhere power you desire.
