That being said, here is a picture of the machine end of my Renaissance C104A hose, with the plastic covers removed, and facing upwards (i.e. The side with the release button on it). The two longer pins are on top, and the two shorter on the bottom.
The wiring connecting to the left-side pins seems to come out of the hose a little lower down than the wiring for the right pins. Also, the wiring for the bottom pins seems to be of a lighter grey than the wiring for the top pins.
I'm not sure if this answers the poster's question? In any event, this is what my hose looks like, and it works properly.
