ordered new classic volt/meter gauge to replace amp gauge. matches others. not sure correct wiring. light was different but ive fixed that.g i assume is grd and is grounded with bracket that hols gauge in. only 1 post to hook to says 1 or I. there is a green wire marked voltmeter in my new wiring harness. does that just go to here or is there more. no directions came with gauge. thanks.

WHERE DOES THE GREEN WIRE MARKED VOLTMETER ORIGINATE.

is this a positive ground system ?

a voltmeter is going to measure the voltage present between the supply side of your battery and ground.

hook it to the green wire and see which way the meter moves. if it deflects to the plus u are ok. with motor running and charging ,look for 14volts.

if it deflects to the minus you will have to isolate the gauge from ground and hook the gauge body to the green wire and wire the terminal on the gauge to ground to get the current flow through the meter flowing the correct way for that meter.

this wire i assume comes from the new kwikwire fuse panel . it comes in the bundle with gas gauge wire,oil.temp.gas,etc, also signal indicator lights,high beam, for instrument panel feeds. 8 wires i think,this green being 1 of them.i forgot to mention im updating to a new kwikwire harness doin away with my homemade wiring,i can do as you say soon. thanks.
