Below you should see 3 pictures of some wiring the enclosed trailer I just purchased has. Long story short, Im using this trailer for landscaping and dont need outlets and plugs inside the trailer for anything. So my question is, do I need to keep any of these converters or wiring throughout the trailer?? Wha is that fuse box for??? The only thing I want to keep working is the dome lights, but will those only work if I keep the wiring or do they work once I plug the harness into the truck?? Or is it smart for me to keep the wiring and outlets incase I ever decide to sell the trailer??
