The voltmeter connection can be made at the battery positive and negative if desired. There are two connections at the back of the voltmeter where you will make your connections. Its block diagram is shown in figure. Butt connectors are stronger and more reliable but wire taps are faster and don t require cutting the original wire.

It reveals the elements of the circuit as simplified forms and the power and signal connections between the devices. Thank you for posting the wiring diagram. I connected up as per your diagram. Firstly dc input voltage is converted into ac voltage by chopper modulator and then it is supplied to an ac amplifier i output of amplifier is then demodulated toa dc voltage proportional to the original input voltage.

Use either butt connectors or the commonly supplied wire taps to connect the voltmeter wires to the wiring harness. It would be nice to get a reading of amps supplied too. Remove the bottom of the dashboard and look for where the wire harness is.
