What fuse ratings feed the ECM circuits shown in this diagram?

Two 15A fuses are shown at the top: fuse box position 24 and fuse box position 14 (the latter used with 3A/T & M/T with cruise control).

Which relays connect to the engine control module in this diagram?

The fuel pump relay (E60), main relay (E61), A/T TCC relay (E81, for 3A/T), and TCC cancel relay (E82).

What connector is the mass air flow sensor on and how is it wired?

The MAF sensor is connector E25 with three pins; it connects to the ECM via Gr/B and other wires, with a B/G ground path and Bl/B wiring shown.

Does the stop light switch wiring differ with cruise control?

Yes. Two E41 stop light switch variants are shown: one for 3A/T without cruise control and one for 3A/T & M/T with cruise control, the latter tied to the cruise actuator and cruise main switch (G/W wire).

What do the numbered footnotes in the legend mean?

1 = M/T, 2 = A/T, 3 = IWATA, 4 = CAMI, 5 = 2-door CAMI, 6 = 2-door IWATA and 4-door. An asterisk note says for 4 A/T refer to the 4 A/T control system diagram.

This is one page (ECM3) of a multi-page Engine Control Module (ECM) wiring diagram set. It shows the ECM's connections (connectors E34 and E33 with numbered pins) to related circuits: the fuel pump relay (E60), main relay (E61), A/T TCC relay (E81, applicable to 3-speed automatic transmissions), TCC cancel relay (E82), stop light switch (E41, shown in two variants — with and without cruise control), cruise main switch/actuator, mass air flow sensor (E25), oil pressure switch (P04), A/T TCC solenoid valve, monitor connectors (E14, for engine/RWAL/A&T diagnostics), the transmission control module (A/T), and the fuel pump (M09). Two 15A fuses feed the circuits from the fuse box (positions 24 and 14). Wire colors are labeled throughout (e.g., B/W, P/B, Bl/B, W/R, G/W, Lbl, Gr/B, P/Bl, P/G, Y/Y, W/Y, B/G, Bl/R). A footnote legend distinguishes M/T vs A/T applications and IWATA vs CAMI production plants, plus 2-door/4-door variations, and a note refers readers to the separate 4 A/T control system diagram for 4-speed automatics. A reader can trace power, ground, and signal paths between the ECM and fuel/transmission/cruise-related components.
