Factory Amp(s) On/Off Button

[08MustangDude]

I bought four of these buttons, so decided to use one to turn the factory AMP on or off.

Soldered JST connectors on for power and light.

Drilled out the blank button:

Installed Switch:

Installed into the bezel:

Wiring everything up:

I did not want the button light to be bright, so rather than use the +12 from the
radio's amp lead, I am using the +5 out result from the resister, so the light is dim,
and not in your face at night.

Drilled and tapped in a ground screw for the button's LED:

Radio on, AMP on test:

Radio on, Amp Off:

Radio on, AMP on:

All done:

One side effect from wiring the LED to the +5 after the resister is; when there are hard bass hits,
at full volume, the light pulses after the hit. If I back the volume off -2, it doesn't do it. I know
why it does it, just didn't expect it.
