Having ascertained that the switch is good, test the wiring harness. If the wiring harness is connected at either or both ends with a multiblock, consult a workshop manual - many manufacturers and enthusiast websites publish schematics online - to learn which wires and which terminals convey which wiper speed signals; draw a plan on a piece of paper showing the wire colors, terminal.
The scheduler maintains a queue of executable threads for each priority level. These are known as ready threads. When a processor becomes available, the system performs a context switch. The steps in a context switch are:
A 3 Position 6 terminal toggle switch can be used in many other applications and in many other wiring variations. Here we’ll cover how to use a 3 position 6 blade toggle to run a 12Volt DC motor or 12Volt actuator in forward and reverse directions.
3-Way Switch Wiring Diagram #4 above, shows the electric circuit source power starting at the lower 3-way switch. 3-Way Switch Wiring Diagram #5 above, shows the electric circuit source power starting at the light fixture box, and the switch wiring leads out to the two 3way light switches.
When the switch is pressed to the right, the opposite happens, so pin 5 is disconnected from pin 4 and connected to pin 3, making the 2 nd connection to the motor live, whilst the 1 st connection from pin 1 is still at ground (0V), so the motor turns in the opposite direction.

Save the context of the thread that just finished executing.
Place the thread that just finished executing at the end of the queue for its priority.
Find the highest priority queue that contains ready threads.
Remove the thread at the head of the queue, load its context, and execute it.
The following classes of threads are not ready threads.
Threads created with the CREATE_SUSPENDED flag
Threads halted during execution with the SuspendThread or SwitchToThread function
Threads waiting for a synchronization object or input.
Until threads that are suspended or blocked become ready to run, the scheduler does not allocate any processor time to them, regardless of their priority.
The most common reasons for a context switch are:
The time slice has elapsed.
A thread with a higher priority has become ready to run.
A running thread needs to wait.
When a running thread needs to wait, it relinquishes the remainder of its time slice.
What Each Wire Color Means for You
If you live in the United States and your home was built after the 1940s (or your outdated wiring has since been updated), you can expect the electrical wires behind your walls to follow certain color standards. Specific colors identify each wire’s function in a circuit.

Just remember, all electrical wires could carry a current at some point, so treat every color wire with equal caution. If you have any hesitations at all, leave electrical work to a qualified professional.

What the Color of an Electrical Wire Means
Black Electrical Wires
This color of wire is used to transfer power to switches and outlets in all types of circuits. Also, black wires are often used as switch legs in circuits, which is the connection linking a switch to the electrical load. Consider all black wires to be live at all times.

Red Electrical Wires
In 220-volt circuits, red wires are the secondary live wires. Like black wires, they can also be used in some types of switch legs. In addition, red wires are used to connect hardwired smoke detectors to the home’s power system. It’s possible to link two red wires together or a red wire to a black wire.
Blue and Yellow Electrical Wires
While wires in these colors carry power, they are not used in typical outlet wiring. Instead, blue and yellow wires are used as the live wires pulled through a conduit. For example, you might see yellow wires as switch legs to ceiling fans, structural lights, and outlets paired with light switches. Then, blue wires are most often used as travelers for three- or four-way switches (for instance, if you have switches at the top and bottom of a staircase that control the same light, that’s a three-way switch).
White and Gray Electrical Wires
If you find wires in either of these colors, you’ve located the neutral wires. White is most commonly used, but gray wires serve the same function. The purpose of a neutral wire is to connect to the neutral bus bar, a conductive piece of metal within an electrical panel that attracts the electric current for distribution throughout the house. White and gray electrical wires can only be connected to one another. While they’re called “neutral” wires, they may still carry a current, especially if the current load in the circuit is unbalanced, so handle these wires cautiously.
Green Electrical Wires
The purpose of green wires is to ground an electrical circuit. They connect to the grounding terminal in an outlet box and run to the ground bus bar in an electrical panel. In this way, green wires act as a failsafe, giving electricity a place to escape into the ground if a live wire within the circuit touches metal or something else conductive. Green wires can only connect to other green wires. Remember, if there’s a fault somewhere in your circuit, green wires could be live, so treat them with caution.
