Took some pics, the aftermarket stereo conversion harness that came in my car had an orange wire labelled "ill", followed it back the the factory radio plug and its a red wire 2nd pin in. The illumination wire on my headunit connector is Orange, but yours could be yellow. here is that pic:
It looks like those wires are backwards (red to orange, orange to red) but they are correct and work perfectly, so i would look for that red wire coming from the factory radio plug. I'm not sure about your new headunit plug though as it looks different than mine.
Mine is just a plug that goes into the new headunit with 4 inches of wire to be soldered/connected to new wires. I soldered my new plug and wires to the old conversion harness that plugs into the factory radio connectors. pictured here:
The plug on the right i believe is for rear speakers.
Next up is the microphone wiring, I went and bought a 4-pin connector that i can pin myself. It's really big but that's all the local store had. My hand is holding the patch harness connector that goes into our headunit, the wiring goes:
Patch harness
White Black Red
Black Red White
Microphone
It's odd that the colors dont match but i tried that and it never worked, if you buy the same mic i have and hook it up that way it should 100% work.
Next, i ran the wires from that black 4-pin connector up the drivers side A-pillar to the boost gauge. I just followed the existing wiring i assume that is for the dome light and map light.
I then zip tied the mic around the boost gauge mount (white bar with two screws in it) and the mic just sits down in there behind the gauge, it's held in really tight so that it wont wobble around in there.
I then drilled a bunch of tiny tiny holes behind the boost gauge right where the mic pick-up is so that my voice gets through clearly, the holes are pretty hack but i will figure something better in the future.
And thats that! Sorry for the huge pics. Hope that helps!
