Yep. AF uses positive to negative flow.
There's no neutral in a DC system, where did that come from?
Unless you know positively where the loose wire is attached safest would be to attach it to a known ground.
Reverse ground sounds like the intention of the system is a passenger vehicle, make sure nothing is behind you when you back up. You want to watch your towed when you're going forward so constant ground is what you need.
