Which engine and transmission are in that. The US versions had the 5.9 in them. Being a ZG I'm guessing this is an export version? I don't think they used a different system but without knowing the engine it could be.

Hmm. Okay, that's a different one. That would be the lower-level Grand Cherokee here. However, the 4.0 is a great engine. The injector wiring is as shown. One side of each has a Dark Green wire that provides power from the auto shut down relay. Then each has a control wire that grounds it through the PCM. They are each a different color for each cylinder Cyl 1 - White w dark blue, Cyl 2 - Tan, Cyl 3 - Yellow with white, Cyl 4 - Light Blue with brown, Cyl 5 - Gray, Cyl 6 - Brown with yellow
Those should be correct as they used a lot of the same engine controls regardless of country.
