The OBDuino was based on the MPGuino, the basic hardware (arduino, LCD, buttons) are the same in the same place. In the MPGuino there is a VSS input and Injector input, and on the OBDuino there is the ISO input/output (for ISO) or it uses the TX/RX serial port (pin 0/1) for the ELM version.

You can take the MPGuino schematic available here: http://spiffie.org/kits/mpguino/more.shtml and modify it with the Eagle CAD software.

Note: the version with the MCP2515 will have some difference in the pinout of the LCD because of how the MCP interface with the AtMega via SPI.
