Data Link & Monitor Connector Wiring Diagram - ECM, RWAL & A/T Circuits

Factory wiring diagram routing the data link and monitor connectors to the engine, RWAL and transmission control modules with wire codes.

AI caption · Photo 16 of 86

This wiring diagram shows the Data Link Connector (F02) and Monitor Connector (F03, labeled 'MONITER CONNECTOR (ENGINE, RWAL & A/T)') circuits. Power comes from fuse 13 (15A) in the fuse box via a White (W) wire. The Engine Control Module connects through connector E32/F01 with Violet/Green (V/G, pin 6) and Blue/Yellow (Bl/Y, pin 2) wires. The RWAL (rear-wheel antilock) Control Module connects via Violet/Red (V/R, pin 3), White (W, pin 7, becoming White/Black W/B), and Orange (O, pin 8) wires. On 4-speed automatic transmission (4 A/T) models, the Transmission Control Module connects with Violet (V, pin 4) and Blue/Orange (Bl/O, pin 10) wires. The Data Link Connector F02 uses pins 12 (V/G), 8 (W), and 6 (B/ground), while the Monitor Connector F03 uses pins 5, 9, 2, 3, 7, 8, 4, and 10. Ground return is via Black (B) wires through connector F01/E32 pin 5 to two chassis ground points (10 and 9). A footnote notes variation '[1] 2-DOOR: IWATA, 4-DOOR'. Readers can trace pinouts, wire colors, and connector locations for diagnostic connector troubleshooting.

Frequently asked questions

What fuse powers the data link / monitor connector circuit?
Fuse 13, a 15A fuse in the fuse box, feeds the circuit via a White (W) wire.
What wire colors connect the Engine Control Module to the data link connector?
The ECM connects with a Violet/Green (V/G) wire and a Blue/Yellow (Bl/Y) wire, passing through connector E32/F01 pins 6 and 2.
Which pins on the monitor connector (F03) are used for the RWAL control module?
Pin 3 (V/R, Violet/Red), pin 7 (W/B, White/Black), and pin 8 (O, Orange) carry the RWAL Control Module signals.
What pins does the transmission control module use on this diagram?
On 4 A/T models, the Transmission Control Module uses pin 4 (V, Violet) and pin 10 (Bl/O, Blue/Orange).
How is the data link connector grounded?
Black (B) wires from F02 pin 6 and F03 pin 5 join and run through connector F01/E32 pin 5 to two chassis ground points, numbered 10 and 9.
