Ford 3.8L DIS Ignition Wiring Diagram - EEC-IV, Coil Pack & Sensor Pinouts

This document is a Ford DIS (Distributorless Ignition System) wiring diagram for the 3.8L engine, showing the electrical interconnections between the crankshaft sensor, camshaft sensor, DIS module, ignition coil pack, and the EEC-IV processor. Connector views are shown looking into the wiring harness. The crankshaft sensor's 4-pin connector carries PIP EEC, PIP S, IGND PS, and VBAT PS signals (circuit reference numbers 33, 35, 55, 56). Five signal lines run to the EEC-IV processor: CID 24, PIP 56, SPOUT 36, IGN GND 16, and IDM 4, with a SPOUT in-line connector in the SPOUT circuit and a case ground shown. The camshaft sensor connector carries IGND CS, CID CS, CID EEC, and VBAT CS. The DIS module's 12 pins are mapped across two connectors: pins 1-6 include VBAT D, CID D, PIP D, and SPOUT; pins 7-12 include IDM, C2D, C3D, C1D, and IGND D. The 3.8L ignition coil connector carries coil drive circuits C2C, C3C, C1C and VBAT C. A note explains that IGN GND is a low-current reference grounded through the DIS module's metal base plate, and proper operation requires a low-resistance ground path. Reference number A12747-A.
