how to stabilize voltmeter reading?

I have a 2-wire digital voltmeter installed using a relay and hooked up through the running lights (wiring details later) but the readings sometimes jump too quickly for me to read properly. I'm not talking big jumps, usually no more than .5 volts, but it's difficult to get a proper read because the digits blur it's so fast. Pre-ignition it's stable.

So, does anybody know how to stabilize the readings more?

I'm using the standard relay everybody else seems to be using.
Pin 87 goes to the white/blue line accessory line in headlight bucket
30 goes to the voltmeter positive
85 goes to black/yellow accessory ground in the bucket
86 goes to the blue running light line in the bucket
Voltmeter negative is also tied to the 85 ground

Is there a different place I could tie into? Possibly solder in a capacitor?

Soldering in a capacitor is the only thing other than getting a shindegen rectifier/regulator that would stabilize your volt meter. or go with an old school mechanical gauge wich would work a lot better.
