for the understanding of the wiring:
both relais are grounded through the ecu. the fuel pump gets power over relais 2. relais 2 is switched by relais 1 and ecu. don´t be confused, by the upside down relais 2.
so, if u have troubble to find the injector wires, u can also cut the wire from relais 1 (coil) to the ecu.
