All regular cables are straight through; it doesn't matter if the connector is reversed, so long as both ends match.

I'd really like to believe you, but, Appendix A of the MDL-BDC24 Brushed DC Motor Control Module Getting Started Guide for the Jaguar specifically says

Cables must be “straight-pinned,” which means Pin 1 > 1, Pin 2 > 2, and so on. This is also referred to as a reverse-cable because the tabs on the connectors are on the opposite sides of the cable.

It would be nice to hear that this is true and that you are specifically having success with cables that do not satisfy the requirements of the manual.
