Critical Notes for Dexter (Vladivostok → Costa Rica → 1992 Diamante)

1. VIN F confirms: 6G72 3.0L DOHC 24V V6, OBD-I, Federal/California emissions variants exist
2. Region matters: Costa Rica-spec may differ from US/Japan/Euro in ECU mapping, evaporative emissions, A/C wiring
3. Verify connector colors/pin counts at ECU (usually 3–4 connectors, 88–104 pins total)
4. Ground distribution is critical — check battery-to-body, body-to-engine, ECU grounds
5. Use a scan tool (OBD-I Mitsubishi) to read live data before rewiring
