I just did this to mine wed/thurs! Using the instructions from fordmods (very handy) I got it all up and running real easy except for one minor problem.
My car is an Nov 92 EB2 sedan, but the only dash I could find was a July 92 Fairmont which didn't have the smartlock led. I checked the wiring using the info at fordmods and to my surprise I found that everything was wired up, including tacho! I managed to pull the smartlock LED from out of my old GLi dash but getting it into new dash is a pain as you would have to remove about 7 nuts which are easy to damage. So I broke out a drill and file to make a hole big enought for it to fit (where it was on my old dash). Did that after 20min, and it worked fine :)
Pulled out the low washer light and it plugged straight in with everything working. Now I need to get my hands on an oil pressure sensor, as no one seems to have one :/
