Update
I am mostly pasting this from another post which has a related discussion:
Actually I just got my dash assembly back in a few minutes ago. I had trouble making it go into place and had to drop the steering column back down again, disconnect the main harness from it and unplug the through-firewall connections, attach the entire harness to the back of the assembly and then I finally got it to fall into place.
I may actually be able to turn the key later today!
I am going to wire a push button for the glow plugs as I hate the automatic control and it and the relay are both bad anyway. So new relay and some wiring and button, connect a few more things underhood, finish up the dash components and maybe, just maybe...
