Rx4r receiver: how to install?

I just came back from Flight Fest, Ohio and I am new to RC planes; well anything RC. I bought FrSky RX4R receiver and am not sure how to install it in my Commuter plane I am building. Not sure which pins to connect my servos to and the engine to. Any suggestions would be greatly appreciated. If it helps I also bought a new Taranis x9 lite controller.

Taranis is AETR, so channel one is Aileron, two is Elevator, three is Throttle, 4 is Rudder.
Look at the Input screen on the 9XD when you make the new model, that’s the channel order. You can mess with it in OpenTX but for simplicity leave it alone on your first model.
