Well, as promised but long delayed (my motto is "procrastinate later", grin), here's
some further information for those that are still interested. I was commissioned late in
2005 to build a cluster for a fellow NATO member and good friend. I was able to preserve
the flexible wiring interconnect (FWI) on this bad boy, which makes the installation
pretty much plug and play with the exception of the oil pressure and water temperature
sensors that must be installed.
To preserve the FWI, simply leave it in place on the rear "cover" of the instrument cluster (IC) before starting any structure mods but after removing all the other goodies. Then using a sharp Xacto knife, carefully trim the pieces that stay from the pieces that get discarded as shown. Be sure to leave too much extra rather than too little, you can always cut off more but it's darn difficult to add some!
The thin copper layer is sandwiched between two thin layers of clear mylar. Carefully peel back enough of the top layer to let you "tack" a small wire to each of the copper traces required. Clean the copper until shiny with some green Scotchbrite or similar abrasive; be very careful, the copper is very thin and tears easily. After cleaning, use a low wattage soldering iron to tack a small (22 gauge) wire to the copper. First tin the wire, then the copper trace, then tack the wire in place. It is vital that you get on and off the copper almost instantly or you'll de-laminate the copper from the bottom mylar which is not good. You also must hold the wire firmly in place after tacking it onto the copper or it will tear loose - ask me how I know. Then use some hot melt glue at the edge of the mylar to secure it and the wire securely to the back of the plastic cover as shown.
That's pretty much it. Be very careful and you'll have success. Take your time with the point to point wiring, be neat (you get points for that), and enjoy your results. Here are a couple pix of the finished product. This one was done in brushed stainless steel.
That's about it; feel free to email me with any questions you might have about the project, I'll try to help as best I can. Thanks for viewing.
