Mobile-ease dissection complete (sort of)
OK - I spent some time with the wiring from the Mobile-ease (ME) unit today trying to figure out what wires go where so that I can install it with an aftermarket HU. Right now the ME is installed with my For Audiophile HU. Here's what I found out:
The ME unit is similar to all other brands of bluetooth car kits. It has a keypad that plugs into the main harness and a microphone that plugs into the main harness. These plugins will not change - they will be the same for any HU you have. The other wires coming from the main harness are the ones that matter. They are:
Red: this is the 12v continuous lead (always hot)
Black: normal ground
Red w/yellow stripe: 12v ignition lead (only hot when ign on)
purple: This has a continuous 4.6v flowing thru it until a call comes in or you initiate a call. This must be the mute wire. The thing that suprised me is that there is constant voltage when your not using the ME. I thought there would be voltage when you were only using the ME, but there is 0 voltage when the ME is being used. I just don't know how mute wires work though. I guess it makes sense.. when the voltage is on, a relay is on which makes the stereo work. When a call comes in, the voltage goes to 0 and cuts power to the speakers. I'm probably being stupid here, but I'm just telling you what there is.
Light grey 'thick wire': This is actually a cover for three wires which are contained inside: a red one; a black one, and one non-insulated silver wire. These are for the speakers - before amplification. What I can't figure out is what each one is for. I cut the red one and there was still sound coming from the ME (I acted like I was placing a call). I cut the black one and connected the red one and there was sound coming from the ME. It didn't seem to matter if one was connected or both were connected. It was slightly louder or 'fuller' when both were connected, but it seems that I only needed one to make the system work. I never cut the silver non-insulated one - it has to be a negative for the speakers I think.
So it seems that you can use either the black or red (along with the silver) to go to an external amplified speaker or a to a speaker wire that will be amplified. It will take more digging for me to find out where the red/black/silver hook into the radio harness, but at least I know those are the speaker wires.
Anyway, hope this helps somebody, and please correct anything I may have wrong. If I find out more I will post.
