I am hoping to install a external led for my LI that will mimic my stir + remote led.
I have found a red/greed led (no flashing) led that may work but i am a little stumped on wiring. This led will be green with the leads oriented one way and red if you reverse polarity.
I get that i can wire the led like the switch for green but I need a little help on getting the red to light upon alert. I can use the mute as my "alert" ground but what could be used as the "alert" positive lead? Would the switch 1 output work?
I am not great with electronics but I imagine all + leads would need diodes. Maybe all leads?

Can anyone help with this project or is it not possible?
