I finally received my quad-C kit yesterday and I am well into the process of assembling it. However, I ran into a problem when connecting the GPS receiver (uBlox). The GPS receiver came together with a short six-pin cable which I assume is for connecting it to the APM. The GPS receiver has a six pin connector which fits the cable nicely, but the connector on the APM is only five pins! Am I using the wrong cable, was I supplied with the wrong cable, or is there some trick I haven't seen yet?
