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.
