My car stereo has a mute input mode; when a certain wire goes to ground, the radio mutes. I want to hook up my LI to this wire so the radio mutes when the LI goes off. Do I just connect the black wire on the LI to this wire on my stereo?
I tried a piece of wire from the existing stereo harness to a ground. The radio went to mute. When I tied the black LI wire into this harness and turned the LI on, I expected the radio to mute when the "welcome" lady came on. However, this did not happen. Does the mute wire only go active when being jammed?
