    I have the grey 2 connector ecu. Need the pinout for it. Online all I can find is the 3 connector.

    Hey Litneon. I really doesn't matter..but it intrigues me. How does the firing of the injectors work? I understand they are always hot and grounded by the ecu in sequence. But what tells the ecu when....

    The injectors aren't fired in sequence. They are batch fired using the tach signal from the igniter.

    The funny thing is, there are two output pins for the injectors that seem like they'd fire in pairs, but then the harness is soldered together up from the ECU.
