This document is a connector pinout diagram for connector C1012 (black), the Transmission Range (TR) Sensor connector used with the E4OD automatic transmission. The upper portion shows the 8-pin connector face with pins numbered 1-4 across the top row and 5-8 across the bottom row, with each cavity labeled by its circuit number and wire color code. The lower portion is a table listing each pin, its circuit number/wire color, and its circuit function: Pin 1-463 (R/W), 4x4 Low-Neutral Sense Circuit; Pin 2-359 (GY/R), Sensor Signal Return; Pin 3-199 (LB/Y), TR Sensor Signal; Pin 4-57 (BK), Ground; Pin 5-32 (R/LB), Power (Hot In START); Pin 6-140 (BK/PK), Backup Lamps; Pin 7-298 (P/O), Power (Hot In RUN); Pin 8-32 (R/LB), Starter Relay Feed. A reader can use this diagram to identify wire colors and functions when diagnosing TR sensor (neutral safety switch) issues such as no-start, no backup lamps, or incorrect gear indication on an E4OD-equipped vehicle. The document itself does not state a year, make, or model; it was uploaded to a 1995 Ford Bronco gallery.
