===The circuits===
Two simple circuits need to be made - one with a button in it, the other with the solenoid in it. Parts of both of these circuits run through the relay.

If you can read a circuit diagram, you can probably make sense of this diagram. If you can't allow me to explain.

;Circuit 1 - "Button circuit" : This circuit runs from the 12v power supply (ie a live in the car somewhere), then through the button, then through the relay's coil, and finally to a ground in the car.

;Circuit 2 - "Solenoid circuit" : This circuit runs from the 12v power supply through the switching part of the relay, then through the solenoid, and finally to a ground in the car.

What Circuit 1 does is when the button is pressed, it completes the circuit, and energises the coil in the relay. The energised coil closes the switch on the Circuit 2 part of the relay. Circuit 2 is now complete, so the solenoid is activated. Circuit 2 will remain complete until the button in Circuit 1 is released.

The numbers in the diagram above in the relay (the box at the top) correspond to the pins on the relay.
