Just have to ask, did you take the firewall bulkhead loose to get uour dash out. I cut the one at the junk yard. Cant find a way to get old one out without destroying my wiring harness
You can remove the dash assembly without removing the wiring harness. This how to remove the 1988 to 1994 dash.
Remove all of the trim bezels for the instrument cluster, radio ,etc.
Remove the instrument cluster and unclip the cluster plug from the dash.
Remove the lower column cover. Drop the steering column down, remove the screws that are on the top of the dash along the inside of windshield. There is one screw under each speaker cover and the rest are between the defrost vent and the windshield
The are 2 bolts on the bottom of the dash assembly right next to the tops of the plastic kick trim panels ( one on each side) that face up. Remove theses bolts and rotate the dash assembly towards the seat. You can then reach behind the dash and unfasten the plastic retainers that hold the wiring harness to the dash assembly. A mirror helps to see the plastic retainers, it is a bit tedious but you can get the dash out with out pulling the harness. Just make sure than any electrical connectors that attach directly to the rash are disconnected .
If you take your time and don't force anything you can remove a dash in one piece with no damage.
If I left out any steps some anyone feel free to chime in.
