BTW here is the way you can usually tell. If you look at the schematic and see a wire going on one side of the connector and nothing on the other, consider flipping it. If the wire colors make more since this way in that the color match closer, it is probably mirror. So on the 69 schematic, if you don't flip, the tan goes to the blk/blue. If you do flip, the tan goes to the blk/tan. Its not perfect but it should make a little more sense. However, before you consider jumpering make absolutely sure (take measurements) or you could burn something up.
