This document is a connector pinout diagram for the instrument cluster connector, identified as C400. It shows an 18-terminal connector drawn as two vertical columns: terminals 18 down to 10 on the left side and terminals 1 down to 9 on the right side. Each terminal is labeled with its circuit number and wire color code. Left-side circuits include 3 LG/W (terminal 18), 12 LG/BK (17), 19 LB/R (16), 57 BK (15), 2 W/LB (14), 296 W/P (13), 60 BK/LG D (12), 16 R/LG (11), and 904 LG/R (10). Right-side circuits include 39 R/W (terminal 1), 31 W/R (2), 977 P/W (3), 640 R/Y H (4), 208 & 208A GY/BK D (5), 215 Y/BK D (6), 450 OR/LG (7), 29 Y/W (8), and 82 PK/Y (9). A reader can use this diagram to identify which circuit number and wire color connects to each cavity of the instrument cluster connector C400, useful for diagnosing gauge, warning light, or cluster illumination problems. The page itself contains no year, make, or model designation; it was uploaded as applying to a 1985 Ford LTD Crown Victoria.
