    I wired in a switch and hid it in the glovebox on an older crown Vic I had. Radio to switch, switch to a good grounded spot behind the dash. Done

    Try just finding a good ground on the radio body.

    You can't just ground the newer units anymore to bypass them. They need to either be hooked up correctly to the parking brake sensor, or bypassed with a relay. Many people use the PAC TR7 but there are plenty of other options as well.

    Pretty sure I ran mine to the e-brake switch. Why is that not working for you?

    Doesn't it depend on the stereo? Some might want to sense 12 volts to mean parking brake engaged, some want that to mean not engaged. You really need to check the instructions for the stereo and then look at the wiring diagram for the parking brake for your model.
