GT6 battery cable color

["Theis, Karl J" <karl.j.theis@lmco.com>]

I'll  admit, this is the most trivial question of the week, but...
        What is the color of the positive battery cable on a GT6 AS SUPPLIED
FROM THE FACTORY?

I think black, but?
 The negative appears to be a braid covered cable.(?)
I am putting an order together for British Wiring in Illinois.  Anybody have
experience with these people?
Thanks again,
Karl
