Part of 1992-1995 Ford Taurus Wiring Diagrams
This document is a wiring diagram for a Ford Distributorless Ignition System (DIS), uploaded to a 1993 Ford Taurus gallery. It shows power flow from the ignition switch (HOT AT ALL TIMES, with START/RUN/OFF/LOCK/ACC positions) through circuit 262 BR/PK and 16 R/LG wiring, splices S108/S109/S170/S171/S172, connectors C103/C149/C167/C168, and the 30A IG COIL fuse in the Power Distribution Box. The R/LG feed branches to charge/power distribution, the Integrated Relay Control Module, a radio noise capacitor (BK ground), and the DIS module and ignition coil pack. The ignition coil pack contains three primary/secondary windings feeding six spark plugs via circuits 850 Y/BK, 851 Y/R, and 852 Y/W. The solid-state DIS module connects through C170/C169 to the Electronic Engine Control via circuits 11 DG/Y and 324 Y/LG, and to the crankshaft sensor (325 DB/O) and camshaft sensor (349 DB, 795 DG, 796 LB through splice S141, 749 PK/BK). A reader can trace ignition power distribution, coil pack wiring, sensor circuits, wire gauges (16 AWG), color codes, circuit numbers, and connector/splice identifiers for diagnosing a Ford DIS ignition system.

Frequently asked questions
- What fuse powers the ignition coil in this diagram?
- The IG COIL fuse in the Power Distribution Box, rated 30A, fed by 16-gauge R/LG wiring from the ignition switch.
- What are the wire colors from the coil pack to the spark plugs?
- Circuit 850 is Y/BK, circuit 851 is Y/R, and circuit 852 is Y/W, each feeding a pair of spark plugs from the three coil primary/secondary windings.
- What circuits connect the DIS module to the Electronic Engine Control?
- Circuit 11 DG/Y and circuit 324 Y/LG run from the DIS module (through connector C170) to the Electronic Engine Control.
- What wires go to the camshaft sensor?
- Circuits 349 DB, 795 DG, and 796 LB (through splice S141) from the Electronic Control Assembly (ECA), plus 749 PK/BK via C169 and 796 LB via C170.
- What is the crankshaft sensor circuit?
- The crankshaft sensor connects via circuit 325 DB/O and receives 16 R/LG power from splice S172.
