Sorry if this has been already been asked, does the Sony 6 CD Changer have an aux port on the back of it as it has a CD/AUX button on the front. I cant find the plug anywhere. Sorry if this is a stupid question :(

The aux input is part of the big (FAKRA) connector on the back. The 3.5mm jack is in your glovebox (top right).

Cheers mate.

When you remove the connector block (quadlock) from the back of the radio the aux connector will be where the green plug is on the photo.

Do a web search for fordwiki and search there for ford quadlock.

Sorry I can't post the direct link here.

now, the pin12 on connector c is mic, im assuming the gnd is audio ground? now i have this as a starting point i will try poking my multimeter about again...

i never knew about fordwiki before, but with a quick glance looks VERY useful. cheers for the info dude!

rev sense wire looks interesting to fit an auto lock anti hi-jack mech onto the titanium too

Far as I'm aware the connectors are exactly the same.

There are a couple of members here that I believe have tried fitting Mondeo radios to a Focus and the only thing that caused problems was the shape of the radios.

They worked fine with the wiring but don't fit the Focus dash.
