has anyone got a set of plans ect to make a didgital dash
thinking scheametric wiring diagram and component list

do a search on this site

There have been quite a few mentioned over the years but few ever get finished (including the one I started but haven't worked on for 6mo)

Dash7 has been stalled for 3 years but there are schematics available.

Our very own "Bob C" made one for his car which he was talking about selling (check out his photo archive)
