Yay, I just got parts in for my Air/Fuel guage, today. It's going to be one of those LED blinking type ones, but nothing compared to Corbins...Directions here.. (most parts can be had for free!)..http://scirocco.dyndns.org/tech/misc/afgauge/af.htmlI have questions for Corbin though (anyone know where he is at?)...Like can you give me a wiring diagram (schematics )of how your guage is?Do you NEED 2 circuit boards?Do you NEED the Heat Sync (Sink, or however it is spelled)?Thanks~Tacoman
