That link does not seem to work.

Ebay responds with "Page Not Responding"

If this Amp meter is going into the vehicle, then order the 12VDC version.

You will need to keep the SHUNT very clean and dry to maintain accuracy. It's a nice unit. The SHUNT is installed "inline" with the 12V that is used to power the electrolyzer. See my edited drawing.

The other two lines get +12V and Ground(negative side of the battery). Make certain of the polarities on everything before attaching power.

Does the unit have switches to select the working power?

The Ebay instructions say "Please specify" in the notes.

I ordered one very similar to this one from Asia Engineer (LCD), & the instructions said it would need a separate power supply than the vehicle (can't ground to vehicle body, & all the pix I see here do not show power from vehicle). I thought, yeah sure, & tried it. It would not work until I used a 9V battery. It is very nice though. But I did also use a relay to power the ammeter that activates from the HHO generator power. This way, I know that if my meter is off, then the HHO relay has not failed closed.
