Find out what you are tapping and see what else is in line with that circuit. There are generally free aux lines in the harness you can use and last resort is to pull a line through the firewall directly from the battery. I would not rely on voltages appearing at different key positions without understanding what you are tapping into. E.G. A CANH line will steady state high if nothing is talking on the bus giving you a positive voltage, but is not a line that can be tapped into. | |

The wire you have tapped must have something (lights or ?) between the ignition or aux switch and the place you connected. | |
