SR3500 Receiver plug in instruction please

[DANALLY]

I am helping someone set up a crawler and he sent me a SR3500 receiver and a DX3c radio. I have a question:

I have no instructions on the receiver. I found the binding instructions on line but need to confirm the wiring. It has an A, T, S, B for the plug in ports. I figured that the T for throttle and S for front steering and the B for bind. Where does his rear steer servo plug into? Is it the A?

Seems like a stupid question but I can't find instructions anywhere...just bind instructions. Thanks!

A=Auxiliary

That should be the rear servo.

Thanks. I thought it might but it never hurts to ask.
