Hi fellow zookers,
I stumbled across what can only be called the Bible to installing a Vitara G16B 1.6L efi engine into a sierra. It goes through step by step and also includes wiring diagrams. See link below:

There are additional wiring diagrams here:

Hopefully this might make things easier for those of you attempting this conversion (which is the only conversion anyone should ever consider for a sierra
)
Cheers
