Factory Amp Turn On/Off Button
I bought four of these buttons, so decided to use one to turn the factory AMP on or off.

Drilled and tapped in a ground screw for the button's LED: https://cimg0.ibsrv.net/gimg/mustang...1f7eccc64a.jpg https://cimg1.ibsrv.net/gimg/mustang...9c0ac290d3.jpg Radio on, AMP on test: https://cimg2.ibsrv.net/gimg/mustang...24d21c5040.jpg Radio on, Amp Off: https://cimg3.ibsrv.net/gimg/mustang...d5505e6ec8.jpg Radio on, AMP on: https://cimg4.ibsrv.net/gimg/mustang...bb0482bffd.jpg All done: https://cimg5.ibsrv.net/gimg/mustang...55e4dc96d5.jpg 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. |
The side effect of hooking the LED power after the resister, was that it pules with bass when the radio is at full volume. I do know why it pulses. If you want to prevent it, install a diode after the resister, then the wire the LED behind the diode. Then the factory amp lead to the diode. The diode will block the surges. https://cimg9.ibsrv.net/gimg/mustang...a984adceba.jpg |
