Bind plugs on Dx7

[robl]

Why does the dx7 seem to have like 3 bind plugs? And do I need to use the included switch harness or can i just plug the bind plug into any open slot and use the receiver harness and battery from the trex600?

You have two options with binding the DX7:

Use the switch harness with one binding plug or place the other binding plug in the battery slot and plug the receiver battery in any open slot (most commonly the throttle channel A.K.A channel 1).
