Please, I need help with wiring

Hi ,

I need some help figuring out how to wire my ESC, Motor, Batteries , Servo and Reciever :)

Here is what I have:

Warrior 9920 ESC
Lehner basic 1600xl
2 - 11.1 v Lipoly 3S batteries ( need to wire them in series for ~24 volts)
Hitec 645 ultra torque servo
Airtronics MX3 reciever

So I have a few questions.....

First on wiring the batteries in series, I have the dean plugs on them now, I guess I have to get rid of them? And then connect the + on battery A to - on battery B, and then that will leave me with one free + on battery B and one free - on battery A? Is this correct? Is there any way to do this without getting rid of the dean plugs?

Ok, I understand the 3 connections coming out of the ESC that should go to the motor, there isnt any specific matchup in order is there? I can just connect any one to any one?

now for connecting the ESC to the batteries, the controller currently is connected to 2 deans plugs, there are 2 red wires going to one slot on dean plug A, and then there are 2 black wires going to one slot on dean plug B, then there is a wire connecting the open slots on A and B. The bottom line is I need to send the ~24 volts from the batteries to the ESC, how do I hook them up, is there a way to do it using the dean plugs?

Last question is related to the connections on the Airtronics MX3 reciever, there are 4 slots:
1 - Steering Servo
2 - Throttle Servo
3 - AUX
4 - Separate from the rest and labeled B/DSC

I assume I connect the Hitec Servo to # 1
Connect the ESC to #2
do I connect the on/off switch to this as well? If so, which slot?
