Let me clarify my query why I'm focusing on those two wires - the injection computer is built inside the fuel pump, and the metering for the actual injection is done inside the fuel pump decided by the injection computer and the fuel to be injected is "pushed" towards the injector, and the fuel inside the injector is "pushed" out inside the cylinder. There are no wires at all to the injectors themselves. So those 2 wires I'm looking at are the final stages I can access is where the actual instructions to inject are carried. How do I find out whether those two wires are pulsed or are digital communications? How do I find out whether the pulses actually mean "Inject now!" or something else entirely? Or do I need insider knowledge for this? Do I make sense?
