Sorry if this is in the wrong section but I'm looking for the wiring diagram for a mk3 Mondeo airbag and mk1 Connect (same as mk6/7 Fiesta ( Looking to change steering wheel on my Connect).

Current combinations are:
Mondeo black
grey/white
brown/black
Mondeo beige
grey/black
brown/red

Connect black
black/white
lilac(?)/white
Connect yellow
black/white
lilac/white

At best I can only hazard a guess which to join but if anyone here know or has the diagram I'd be very grateful.
