Is there a way to test different wires to see what they are for? I have a wire that is wrapped in tape, it is dangling and it has an electrical connection at the end of it. It is in the engine compartment on the passenger side and I cannot follow it. Is there a way to use a multimeter to check current, or at least narrow it down to an area. I am not a good electrician, but Im trying.

If you want a picture I can get it.
