Mobile Phone Hands Free System Wiring Harness

[cww102174]

This is a very interesting post I am will probably try this myself soon. Have a question for you guys. I have a 2000 LS w/ the factory phone that I pulled out. Can this port be used so that I don't have to pull the radio out or are these cables going somewhere different?

Now that is interesting! I think a wiring diagram would answer that for you. I'll have to look and see what it shows.

I am excited to try this, if it works then I may go with a sun visor microphone setup.

JOEGR, let me say that you are the man, I have just succesfully hooked up my bluetooth kit and it rocks. I can confrim that on a 2000 ls sport that pin 13 is the mute, and pin 11 and 12 are the input. I put the unit right ontop of the glove box but under the dash. If anyone has any questions feel free to ask, we will be happy to answer them for you.

Nice work man. Post s how-to/tech article or at least some more detail, including the motorola kit you used. So it was pin 13, not 10?

Thanks Joegr.

Does the caller id actually come across the radio screen?

 

[hockey930]

good call there, you are corrrect it was pin 10, I was a little cold and excited when I posted earlyer.

The answer's no on the caller ID. This method of adding the phone does not use the SCP lines, so there is no messaging between the radio and the phone. Ford's add on kit does use the SCP, but I don't think it displays anything on the radio either (other than "PHONE"). The only thing gained that I know of by the Ford kit is that the Phone/Mute button on the radio can then be used to start a phone call. If I ever have the time, I would love to crack the SCP bus for the whole car. I think that a lot of features could be added or modified just by having a controller send the right commands on the bus. As it is, I've had to make modifications the old fashioned way by finding the individual control signals. One that I've made to my Grand Marquis (and will make to the LS when I get time) is power control system that > 1. Powers up the radio and the window controls when the car is unlocked by the remote. (They then stay on for a 5 minute timeout or till the key is turned on then off.) 2. Keeps the radio and the window controls on after key off till the driver's door is opened and then closed (unlike the factory setup that shuts off as soon as the door is opened.) 3. Unlocks all doors after the key is turned off and the driver's door is opened (from inside only). 4. Turns on the radar detector when the car is in gear. Didn't mean to go on like that...

that is pretty interesting.. i have an aftermarket cd player (pioneer).. i wonder if i could still do something like this on my 2000 ls. also i noticed that when i installed the aftermarket cd player now when i shut off the car.. the cd player shuts off right then not when the door is open.

i may switch to the alpine oem cd player, will this give me back access to the disc changer in the glove box and steering wheel controls? also do they play mp3s on that unit? can i even install that unit on a car that didnt come with the alpine setup?

sorry 1 more question - does the alpine oem unit come with preouts for subs with sub control and if so does anyone know the preout of them?

thanks for all this information,

matt

ls4me posted somewhere about that. The timer for the radio is actually in the factory head unit, so the delayed off doesn't work for aftermarket units--it's literally no longer there once you yank the factory unit. I don't remember if he found a way to make it work for aftermarket equipment.

I'm not sure what would be the point of activating the window controls when you use the remote to unlock the car, as holding the unlock button down on the factory remote will roll down all of the windows. Number 2, though, would be terrific--there are times I'd like to keep listening to the radio even after I open the door. Number 3 is available on the new CD3 cars (Fusion/Milan/Zephyr), if you have access to one.

The only thing that causes, is that when you hit the phone mute button, the radio says no phone and won't mute. Everything else works. (You only get the no phone message if you do have a phone hooked up, oddly enough.) I still haven't found my notes on the 04 radio.

joegr -

Are you saying that if you do this mod you lose the ability to mute the stereo? Like if you have a hands-free installed with the mute wire linked to Pin 10, and you hit the mute button it will say "no phone" and NOT mute the system? I'm confused because if it does not mute the stereo signal (CD, radio, etc) then how does the hand-free audio come thru? Or are you saying it does not mute until you press the mute button ON THE HAND-FREE? (that would make more sense and in line with what you wrote - mute on radio no longer works but the radio itself mutes when the mute/start call button on the hands-free is pressed).

If the factory head unit mute button does become useless ('no phone' message) I'm assuming the steering wheel button is the same, no?

Thanks for the great work. Anyone else who has a comment/suggestion on this please do so.

 

[joegr]

Let me see if I can explain this one clearly, since it is not entirely expected behavior.
1. Once the phone is installed, anytime the phone is active (receive a call, or make a call), the original audio source on the radio is muted (in the case of a CD playing, it is paused), and the radio plays the phone audio through your speakers. [Note that this is not the exact same behavior as pressing the mute buttons.] The volume control on the radio adjusts the phone volume. Note that if the radio was off when the phone was activated, it will come on by itself, even if the key is off.
2. When the call is ended, the radio switches back to whatever it was doing before. (If it was off before, it goes back off. If a CD was playing, it resumes from the point it was at before the call. If the radio was on, it goes back to radio.)
3. Each time the car is started, the manual mute buttons on the radio and the steering wheel work the same way they always had. After the first time the phone is used (call made or received), the manual mute buttons stop working (other than to display "no phone." Using the phone itself will still mute/switch the audio.

Excellent explaination. That #3 is quite odd huh.

Thanks man.

 

[MiStArEdX]

Now is there anyway to get the beginning of #3 to stay that way. I would just like my MUTE button to MUTE. My 2000 LS came with Noah's flip phone. Everytime I use the mute button the phone activates (but I don't have the phone activated, does that make sense ). Anyways I don't want that piece of junk but my mute button says "NO PHONE" when I disconnect it (and no MUTE). With the phone connected, I get #1 for about 10 sec then #2.

I think in one of your first posts Joegr you say something about grounding a wire. Could you tell me what wire it so I can try un-grounding it.

I just want a normal MUTE button.

"The 2000 radio had three connectors (only two populated on some models). The cell phone connections were on the 20 pin connector. Pin 10 is the cell phone in-use signal. Connect the mute output from you handsfree kit to this. Pins 12 and 11 are cellphone audio inputs (12 positive, 11 negative). Connect the speaker output from the handsfree kit to these. Sorry I don't have the pins numbers handy for the 04 radio, but other than the pin numbers the connections are the same" - Joegr

How do I reverse this......

 

[MiStArEdX]

PS....I've tried asking people at work because they used to install phones in the Grand Marquis (back when Noah drove them from the ark) but last guy to do them retired back in March.

 

[joegr]

First, let me say that I haven't worked on or had a car with the factory phone installed, so read at your own risk. When you say that you disconnect "it", what is it that you disconnected? There is no single wire that remains grounded all the time, so that is not your problem. I think that your problem is that the radio knows that there is a phone attached because it is communicating with it via the in-car data network. You need to find the electronic module for the phone that is built into the car. I have a 2004 service manual, and it doesn't give a location since the factory option was dropped before 2004 (a dealer installed option remains). I have heard that it is somewhere in the trunk behind one of the side covers, but I do not know this to be fact. If you can find it, disconnect it completely. After this it may be enough to turn the car off and then back on for the radio to realize there is no longer a phone. If not, you might try disconnecting the battery for a few minutes. Those are my best guesses on it.

 

[MiStArEdX]

First of all, thanks for the quick response. I when I say "disconnect" I mean the phone itself. If I was to be charging the phone, that is the cord I disconnected. (It plugs into the phone like a charger would).
I had went to the dealer and told him what I wanted. What they did was have the phone connected but hidden inside the centre console. When I pressed the mute button, the phone would come on and it would MUTE the sound until I pressed the button again. This acutally worked for about 3 weeks when the phone got accidently disconnected. I went back and they can't remember what they did so now I have your so called 3 step program in the last post.....
I did this a while ago and just lived with it but I stumbled across this thread and decided to give it another go.

I had talked to like 15 different people at Ford about this and NO ONE could help me. And then they wonder why no one wants to buy their cars
