What wire colors are used in the Nissan starting system circuit?

The diagram shows W (white), B/Y, W/R, G/Y, B/L, G/B, B/R, R, and B wires connecting the fuse block, ignition switch, inhibitor relay, inhibitor switch, battery, and starter motor.

How does the ignition switch operate in each position?

The switch table shows terminal 1 connected in ACC, ON, and ST; terminal 2 in ACC and ON; terminal 3 in ON and ST; and terminal 4 in ST only.

What is the difference between automatic and manual transaxle starting circuits?

Circuits marked (A) for automatic transaxle models route through an inhibitor relay and inhibitor switch (wires G/B and B via the battery cable), while (M) marks manual transaxle model wiring.

What connector numbers are referenced in this starting system diagram?

Connector references shown are 71M, 50M, 26M, 15M, 14M, 13M, and 55M.

What components are in the starter power path?

Power flows from the battery through a fusible link (W and R wires) and battery cable (B/R) to the starter motor, with control via the fuse block, ignition switch, and (on automatics) the inhibitor relay and switch.

This is a scanned page from a Nissan factory service manual electrical section (page EL-15) showing the Starting System Wiring Diagram (figure SEL504I). The diagram traces circuit paths from the battery through a fusible link and battery cables to the starter motor, and from the fuse block (a 15A fuse position is indicated) through the ignition switch to the starter circuit. An ignition switch continuity table shows which of four terminals are connected in OFF, ACC, ON, and ST positions. For automatic transaxle models (marked with an 'A' symbol), the circuit routes through an inhibitor relay and inhibitor switch with wire colors G/B, B/L, B/Y, G/Y, W/R, and B identified; manual transaxle model wiring is marked with an 'M' symbol. Connector reference numbers 71M, 50M, 26M, 15M, 14M, 13M, and 55M appear along the harness paths. Wire colors include W, B/Y, W/R, G/Y, B/L, G/B, B/R, R, and B. The left margin shows partial text from an adjacent page including battery specifications 75D31R(L)-MF and 95D31R(L)-MF and a 30(A) rating. A reader can learn the complete starter-circuit wiring path, wire colors, connector numbers, and ignition switch terminal logic for this Nissan model.
