IIRC It's either or not both the brown/white wire from the ignition switch is for the gauge set up and it has a built in resistance (10 ohm) Delco recomends on models with a gen light that the reisistor wire be installed parallel to the gen light circuit but I don't think GM did this. So simply connect the existing brown wire to an ignition source but you'll have to add a 10 ohm resistor.
