Pickup up a 1 ohm 10 watt resistor from a place like radio shack. Looks like this:

Connect some electrical line(I used 18 gauge wire) to each wire protruding from the ends of the resistor. Some people solder; I wrapped the wires together and then wrapped in electrical tape. Used about a 1 ft. length of wire on each side. youtube test leads are much longer than mine. I was concerned that excess length would increase resistance and skew readings. On the end of each wire, connect an alligator clip large enough to connect to batteries negative post. Walmart sells a set of these(red and black) for $2 and change.
Remove batteries negative cable. Connect one alligator clamp from your test lead to the negative cable and the other to the negative post. In my case, this sets off the alarm. I have the horns disconnected, but see the lights flashing, indicating this process has activated the alarm. The cars lights flashing stops after awhile. I wait 10-15 min for things to go to sleep, then connect my meter with small alligator clips on the meters probe sticks to the wires coming out of the resistor - one meter lead on one side of the resistor; the other meter lead on the other side of the resistor. Set meter to millivolts; then turn on and take reading.
