wiring question

Connecting the black and red to each other bypasses the amp gauge, and is probably why yours were done that way.
Keep in mind that if you decide to swap the gauge for a voltmeter that you can’t connect it the same way.
The volt meter will have to get it’s 12v supply from a switched ignition source for the positive and it’s ground from the cluster or dash metal.

Hello sir,

I just switched my amp meter to a voltmeter. I get that I need the voltmeter power from the ignition and plan to work on that. Does anyone know if there is an easy stop on the gauge cluster to get ignition power without cutting into the wires from the ignition (behind the key)?

Additionally are you, or anyone else, familiar with where the ground is on the back of the cluster?

Additional I planned to cut and sodder the old amp meter eyes to complete the positive circuit without any concerns of it shorting out, however has anyone come up with a good use for this connection?

Thanks all

Thanks
