Best regards

Hi Jim,


Attached is the original manual (probably center diff only Front diff is very similar) and wiring diagram.

The FFD controller was replaced in late 1997 by the TC60/TC75 this is also now obsolete but I think we can stil make them and most Group A Escort upgraded to this package with A DA98 Logger and DA36 screen now replaced by DA99L2 and DA37.

Originally the FFD Diffs used DISP communications. We can upgrade the units to work to GWv4 if the they have the original diff controller. Cost for that is £150 per unit + GWv4 licence.

Regards
