To install the advanced mute, I had to cut off the two plastic wiring plugs on the mute connector, and splice the wires directly into the wires going into the radio's wiring harness. I cut the 8 speaker wires going into the stereo (leaving enough room to make the splice connections). Then I connected the end going into the radio to the corresponding line on the mute connector meant to be plugged into the radio, and connected the end heading off to the speakers into the corresponding line on the mute connector meant to be connected to the speakers. The wires on the mute connector are labelled (front-right neg, rear-left pos, etc., etc.), which made it pretty trivial to match up the wires to the wiring diagram for the head unit.
To make the connections, I just bought some butt-end splice connectors from Radio Shack (shove the wires into each end and crimp them down with pliers to hold them together).
A more, er, robust solution would be to locate a custom wiring harness for your particular head unit. I actually found a few options in that regard by digging through the Mini2 threads, but decided to be impatient and just wire the thing myself. You'll need the wiring diagram for the H-K unit, though - the one in the DIY is for the Alpine unit.
Yes, I have my mike outside the sunroof control panel, stuck to the gray plastic. The mike color is almost exactly the same as the sunroof panel, so it doesn't stand out much at all. I would think that if the mike were inside the little plastic grill on the panel, your voice would get muffled quite a bit. |
