The check engine light is easy to wire up. One side of the lamp goes to a 12v source (the 7.5A Gauge fuse in the stock setup) and the other to the pin labelled "W" at the ECU (see the EFI section of the TSRM for the pinout).
Some codes will set without the engine running... it's always worth checking.
