Its a must have if you're doing anything with electronics. Its like trying to cook without an oven otherwise.

Connect the black wire into the COM socket. Then the red wire into the V Ohm mA socket (like the picture). Turn the dial to Volts DC, range 20V (thats the area slightly counter clockwise from straight up).

Stick the black probe from the tester to a ground pin, or in the absence of a ground pin, stick it to anything big and bare metal that the electronics are connected to on the car. Stick the red probe from the tester onto each pin Doddy is talking about, it should give you some readings.
