[Adam Bradley]

Any ideas how I might go about doing something like this?
Optoisolation a good idea?

Schematics anyone?

All I have is questions - no answers yet

Well here are another two questions. Which car, which ecu? I've seen ones

All I really want at this stage is voltage level conversion.
