The injectors should all be getting power from the same wire, and then they will be grounded through the ECU in pairs.

So in your case it looks like:
W/BL is the power wire
BL grounds Group 1
Y/BL grounds Group 2

I don't know why Y/BL has other wires attached to it though. Seems odd

fitting a new motor, need some help with wiring for the injectors.
Somebody has linked the injectors together, found a broken wire in the loom, that i can rejoin.
after further investigating i have found that three wires come from the ECU W/BL, BL/SIL and Y/BL the BL/SIL and Y/BL are joined together into one wire BL/SIL, further down the loom i have two Y/BL wires joined to BL/SIL feeding Injector 4 & 2 and the BL wire feeds 3 &1 injector ?????
The W/BL wire is linked to all four injectors as well. this does not make any sense at all. can anybody help???
