Plus they likely have sandwiches....

Those diagrams referenced above explian how to connect things - this gets wired to that, etc.

Some other things you should know:

Wire: try to get type MTW wire for your wiring. This is the kind of wire you'll find in cars or small appliances. It must be stranded, but the kind they use for industrial wiring such as THHN and is really a little too stiff for convenience. If that's all that's available though, it's not too bad. Hey local electrical supply house will have good wire at reasonable prices, maybe they'll even donate some if you explain that you're on a robotics team. Stay away from places like Walmart and discount stores that don't really sell wire for a living, that wire is junk.

Wiring the CIM (drivetrain) motors: use number 10 wire to go from the power distribution board to the motor controller, and from the motor controller to the motor itself. Try to use roughly equal lengths of wire from side to side left and right or your drivetrain may not drive as straight as you like. Check last year's rules for the minimum wire size for everything else

Signal wires: the kit comes with three conductor wires for the control signals. This control signals for the motor controllers are called PWM signals, but the same wires are used for controlling spike relays and many other systems. Although you can put your own connectors on the ends of this wire, you'd be better off buying them premade

The rest: it would be a good idea to check last year's rules to get a good idea of what kind of other requirements there are, such as circuit breakers. You can find these on the FIRST website. Let us know if you can't find them.
