Toyota MR2 Wiring Diagrams — All Generations
Factory OEM electrical wiring diagrams for all three Toyota MR2 generations: AW11 (MK1, 1984–1989), SW20 (MK2, 1989–1999), and ZZW30/MR-S (MK3, 1999–2007). Essential for engine swaps, standalone ECU builds, and chassis fault diagnosis.
The Toyota MR2 spans three generations, each with distinct chassis and engine configurations. The AW11 (MK1, 1984–1989) used the 4A-GE or 4A-GZE supercharged four-cylinder. The SW20 (MK2, 1989–1999) stepped up to the turbocharged 3S-GTE or NA 5S-FE — the most popular generation for engine swaps including 1UZ, 2JZ, and K-series. The ZZW30/MR-S (MK3, 1999–2007) uses the 1ZZ-FE inline-four in a lightweight roadster package.
SW20 and AW11 EWDs are available now. ZZW30/MR-S diagrams will be added — request a diagram if you need one sooner.
