This document is a connector pinout diagram for connector C240, which plugs into the instrument cluster. It shows a 16-pin connector drawing with each cavity numbered 1 through 16 and labeled with its circuit number and wire color code (e.g., 305 GN/Y, 52 BK, 20 W/BK). Below the drawing, a three-column table lists each pin number, its circuit designation with wire color, and the circuit function. Functions covered include instrument cluster ground (pin 1), illumination lamp dimmer control and power (pins 2-3), liftgate open input (pin 4), tachometer input (pin 5), oil pressure gauge input (pin 6), malfunction indicator lamp input (pin 7), fasten seat belt indicator input (pin 8), transmission control switch input (pin 9), anti-theft indicator input and power (pins 10-11), air bag indicator input (pin 12), fuel cutout indicator input (pin 13), right turn indicator input (pin 14), door open input (pin 15), and alternator output low input (pin 16). A reader can use this document to identify which wire and color corresponds to each instrument cluster signal for diagnosis, gauge or indicator troubleshooting, or cluster swap wiring work.
