Mazdaspeed3 gen1/gen2 Wiring Discrepancies

2 Attachment(s)

From what I've been reading, the location of the ECU wires to be tapped are the same between gen1 and gen2, with only the colors of the wires being different. But looking at the diagrams (attached), the fuel injector relay and the injector +\- show different locations. Is the gen 2 diagram correct?

How so? This is the first I have heard of this. Is this a brand new system?

The system doesn't start up?

Post your serial number of the system.
