As you are probaby aware, the dash lights are not fused and a simple goof can cause a costly/time consuming repair. I did this on both the 911 and 914 (after smoking a few wires in the 911). I did a search here and couldn't find anything but might have missed it. Anywho - here is a good piece from PPBB on the process because the wires you save might be your own... http://forums.pelicanparts.com/porsche-911...stallation.html
Happy T-day
