Toyota↔Bosch equivalence assumed (both EUCON 26-way), not cross-listed — verify. |
| ECU power / ground terminals (pins 1, 9) | Bosch 1928498807 (terminal); seal 1928301086 (Ø3.4–3.7) or 1928301695 (Ø4.0–4.5) | BTC 4.8 (4.8×0.8) | 2.5–4 mm² wire | All gens | Tesla uses 4 mm². Yaris AVS 3 (~3,3 mm²) |
