I'm about to install a 2d system to my Subaru Impreza my00 WRX, but am slightly confused about which way round the red and green wires from the FIA2 unit should be piggybacked to one of the fuel injectors.
Here's a link to a .pdf containing the correct wiring diagram for my car (wiring diagram at the end of the document) - If anyone could have a look and tell me which ecu pins i should be connecting the FIA2 to, it would be greatly appreciated
