Use only a voltmeter or LED based test lamp (that uses a very small current) to test
the existence of voltage in a wire or accessory. Do not use a regular test lamp to test
the existence of voltage in a wire. These testers take quite a lot of current and may
damage the equipment in the vehicle (for example it can trigger an airbag or damage
a communication bus).
When you want to test the voltage on a wire, do not expose the existing wires or use a
sharp edge to make an electrical connection to a wire through the insulation sleeve
around it. Make the connection at the end of the wire, near the connector.
Do not insert the multi-meter probe tip into the female pin in the connector. This may
widen it and prevent a proper connection when the male connector is plugged in.

The correct way to connect the probe of a voltmeter or tester to the connector is
