1 or 2 of those wires are probably for lighting and should marry with others nearby.
Of the remaining wires, 1 or 2 may also connect to busses for the ground or positive.
That leaves the signal that should remain separate and head toward the engine room.
After reading Diver Dave's next post, I like the gray wire now.
