I did the same thing, I took off the old dash and put on a new one. When taking off the old one I made a wiring diagram and took pictures of the gauges, but forgot to take a picture of the speedometer and flasher. When I put it back together I used the Bentley manual and a wiring diagram. Car started great and ran great; however, the windshield washer doesn't work, the fuel gauge doesn't work, and the ampmeter gauge is reading backword. I think that I may have put the wrong green wire on the wrong connection on the voltage stabilizer (back of speedometer) as the windsheild washer wires were not hooked up previously and they carry a couple of the same colored wires that hook up to the stabilizer. Any suggestions out there to fix properly? Thanks in advance, as I really don't want to tear the new dash out again!
