1999 Ford Crown Victoria Starting Circuit Wiring Diagram - Starter Relay & DTR

This document is a starting circuit wiring diagram, uploaded for a 1999 Ford Crown Victoria. It traces the starter system from the Battery Junction Box (30A fuse, position 2, hot at all times) through circuit 37 (YE) via splice S127 and connector C292 to the ignition switch (START/RUN/OFF/LOCK/ACC positions). From the ignition switch STA terminal, circuit 33 (WH/PK) runs through splice S267 (with a branch to the Driver Door Module, diagram 57-1), through connectors C105F/C105M and C173M/C173F, to the Digital Transmission Range (DTR) sensor, which permits starting only in Park or Neutral. Circuit 32 (RD/LB) then continues through C168, C161M/C161F, C128F/C128M and C103M/C103F to energize the Starter Motor Relay in the High Current Relay Center (terminals 86/85 coil, 30/87/87A contacts, grounded via circuit 57 BK at G102). Relay output circuit 113 (YE/LB) feeds the starter solenoid (pull-in and hold windings) at C1018, which applies battery voltage to the starter motor. Battery feeds are shown via circuit 2037 RD (C138/C140) with grounds 2057 BK at G100 and G103; power distribution is referenced to diagram 13-1. Grid references such as 151-1 A8, 151-1 B10, 151-3 B1, 151-2 C1, and 151-1 A1 are included for connector and component locations.
