How to remove dash
The column can be lowered out of the way of the dash ( just unbolt it from underneath the dash). You would need to unplug the harness from the back of the dash.
I have always found it is easier to SLOWLY remove the dash in case I have forgotten something so I don't damage anything. When the dash is completly unhooked it is very easy to remove so if something seems stuck, don't just tug on it.
