I have recently installed a nokia blue tooth car kit to my EF Fairmont Ghia. It has the ability to mute the factory system, however, when looking a the wiring on the factory premium system, there is no light green wire, as per the ford manula and ur list for the pin outs on the website. My q is, you guys have listed the pin as pin 6, on plug 1, how to i count which pin is no 6. Thamk

Looking at the above picture, pin number 6 is

Connector Number 1
Top Row
Last pin on the right
(The pin right next to the Number 1)....

I am not 100% sure if Ford added this Light green wire on EF Series I, or even EF Series II.
It was added for EL Models, but all Premium Sound Decks Support the telephone mute (So I have been told).....

Which might mean that you may need to shove a wire in to the back of the connector to get this working.

Let me know if there is a wire there or not, so as I can update the doco...

P.S. If you want to add the wire in cleanly, check out the Adding VGA Connector to BA Premium ICC

This doco shows you how to add a wire to the Ford Connectors.
Lemme know how it all goes.

Nope, there is no wire there, mine is a feb 96 EF11 5.0 Ghia and she doesnt have anything remotely looking like a green wire, will work on it this afternoon and get back to u if it works.
Cheers

Note: you'll need a relay to get it to work. Its the reverse of most muting systems, (requires power, rather than going to ground)

DF and DL LTD comes with pre installed phone wiring with the premium system. My brother installed a phone kit in My EF Fairmont ghia when it was his and i'm more then certin he swapped something from my parents DF LTD to get it to mute. Try to get a copy of some LTD wiring diagrams that mite help.
