Thanks BR, there really isn't a need for a whole harness, analogue swaps really are not "That" difficult, just really more time consuming. All the the "stuff" is there in the digi cars, it's just a matter of getting everything in the right places. I spent the day with a handfull of jumper cables, a DVOM, and Pandora turned up loud in the garage. Took more hours than I would have liked, but I now have a temporary dash in place as I can't seem to turn up a proper GL dash:
Does suck in that the Odometer doesn't work. And I still need to get the analogue sending units for the fuel and temp to work right. However I do have a speedo, and all the telltale lights work. So now with just a little polishing things up here and there, I'm going to have a manual tranny EA81 Turbo for a daily driver!!
