Recently got a new pixhawk and have a perplexing question with regards to cables for the GPS, 3DR radio and the power module. All 3 units have a 6-pin connector on the Pixhawk (GPS, Telem 1, Power) and all 3 have 6-pin connectors on themselves. However, the system came with 1 6-6 cable and 3 6-5 cables. The 6-5 pin cables only have 5 wires and skip the 5th pin on the 6-pin connector. So, what cables do I use to connect these units to the Pixhawk. With only 1 6-6 cable, can't connect the other 2 units.
