Well Bean,

I was not referring to the wires going to the connectors on the injectors themselves, but to the injectors as a set.
From the ECU you have 3 wires (Plug Y, pins 6, 4 & 9 in the 'parrot' manual).
One goes to the injector+ side and is likely a voltage reference for the ECU to make adjustments with, the other 2 are grounds, which are connected together in the manual right beneath the injectors (page 85), and which are connected together in the oem ECU as well.

I couldn't figure out what #10 and #20 was referring to.

Since it is a full sequential setup you're researching I would suggest unplugging both the ECU as well as all injectors, and then check for continuity between the injector grounds on the ecu side and the injectors themselves...

It is still a moot point, if you want full sequential, you'll need to run new ground wires from the injectors to the ECU (at least 2 new wires, if you can find and sever any possible links between the 2 existing grounds.)
You could make it a reversible process by adding an extra connector with which you can reconnect everything together should you need to revert to an OEM ECU.

If I can find my wiring loom I'll measure it through for you, although I have a MAP harness, and your car is an AFM equipped model if I'm not mistaken.
