1G 1990 Engine ECU MPI Circuit Diagrams

With the 1990 model year being the trial production there were many differences from the later years. These diagrams help document the Early 1Ga ECU and MPI 4G63T wiring. The later model year diagrams are easily available but these weren't.

Thanks for sharing. 90s are a love/hate relationship.

These might be useful as well. I haven't checked to see if they are different from the later cars or not, but if people are looking, having the power distribution diagrams right here might help.
