electronize speed controllers

hi guys, i am new to this robot building lark and i have got a few problems, i bought 2 of these speed controllers a while back, unfortunatley i have lost the instructions as to which color wires go where, i have also noticed that on one of the leads that i think goes to the tx, there are 3 wires and only one of them is connected to the little plug, the other 2 wires are not, is this normal, my other problem is how to fire the ram, do i just wire the solenoids to the tx or is there another way of doing it, any help would be great thanks guys

Red wire goes to positive battery terminal
Black wire goes to negative battery terminal
Yellow and blue wire go to the motor- it does not matter which way round they go.
It is normal for the rx wire not to be connected, just find a servo and plug the wires into the connector in the same order as they are on the servo wires.

All the wire placements are written on the front but here they are anyway...

Red - Always positive
Black -Negative
Blue & Yellow - To motors in any configuration

The reason that only one wire is attached on the TX leads is so you can match the wire arrangement to your TX. Look up your TX's manual and it will tell you which way round to put in the wires.

Hope that helps

EDIT: Quick typing Max!

The Red, White and Black wires should all be in the plug.

The Yellow and Orange ones that come out the back just turn the BEC on or off. On one of the ESCs connect these, leave apart on the other (you only need one BEC)

The thick gauge wires are for your motor and battery connections. Do not mix up the battery polarity!

thanks guys, great help,

And to fire your valve you need to control the solenoid with a relay (eg. Battle switch from robochallenge) or connect it to a micro switch which can be opertated with a servo (press the button with the servo arm)
