FrSKY X8R and X4R receiver connections

The latest receivers for the Taranis are the X series. They are  telemetry, S-Port and S-Bus capable.

I don't really understand S-Bus at this stage, it has something to do with connecting another receiver for more channels or many S-Bus servos into one plug.

However I do use the S-Port for connecting telemetry modules. On the X8R the S-Port is a servo style connector - easy. But on the X4R the S-Port is a different 4 pin socket. A 4 pin plug with 4 bare ended wires is supplied so you need to make up your own servo style plug.
