Hi Kevi,

It's been a while since I was into that part of the loom but from memory I belive that the green one is the negative switching line back to the ECU and the white one is the live supply to the injectors.

The injectors are batch fired,and if I remember correctly inside the wiring loom all the positive lines from the injectors converge into the white wire and all the negative lines converge into the green one.

When you think of all those injectors running in paralel like that,it goes to show how much current the injector transistors in the ECU are shunting around so if your doing a full from scratch rewire be sure to get your supply for the injectors from somwhere suitably substantial.I belive it was originally taken from the fuel pump relay or there abouts.

Hope that helps.

 

All the very best

O.T.

green and yellow is earth, if it is the injector wiring then it'll be connected to the ecu, the other would be 12v from the relay pictured.
