3DR Radio V1 correct cable?

What cable works for the 3DR radio V1 telemetry port. This radio has 6 output pins and it came with two cables. One is a 5 pin 4 wire and the other one is a 6 pin 4 wire.

5 pin for APM, 6 pin for PIXHAWK

I understand about the 5 pin and 6 pin connectors. The cables that came with my radios only have 4 wire with one have a 6 pin connector and the other have a 5 pin connector. This is what I ordered.
