might be able to identify by the colour of the ecu plugs and also the injector plug colour.

How can I work out what gen 1GGZE I have? Also having a quick look at the wiring it only has 2plugs for the computer and no check connector does that sound right?

hello
All 1GGZE computers have 3 plugs but the third plug is part of the cars wiring; not the engine wiring. Easiest way to tell is by looking at the coil packs. If the coils are mounted in between the rocker covers than it is late model. If they arre mounted at the back of the engine on a bracket then it's an early model. Also, the late model has a small round TPS whereas the early model has a large square TPS.
Yellow computer plugs, coils mounted at rear. gen 1 I was hoping to get a later model engine! What internal changes are made between The gen's? Is it only different cams and a better programed ecu to make the extra gains fbetween the gen1-gen2?
