This document is a schematic diagram showing cylinder numbering and ignition coil pack terminal locations for the Ford 4.6L V8 engine across three production spans: 1991 thru 1993, 1994 thru 1997, and 1998 and later. A 'FRONT' arrow orients the diagrams, indicating the front of the vehicle. In all three diagrams, the cylinder numbering is identical: the left (driver's side) bank is numbered 1-2-3-4 from front to rear, and the right (passenger side) bank is numbered 5-6-7-8 from front to rear, with cylinder 1 highlighted. The 1991-1993 diagram shows two coil packs: the left pack terminals arranged 1 and 3 on top, 6 and 5 on the bottom; the right pack terminals arranged 7 and 8 on top, 4 and 2 on the bottom. The 1994-1997 diagram shows revised coil pack terminal arrangements: left pack 6 and 3 on top, 1 and 5 on the bottom; right pack 7 and 2 on top, 4 and 8 on the bottom. The 1998 and later diagram shows only cylinder locations with no coil packs pictured (coil-on-plug design implied by absence). This is useful for spark plug wire routing and cylinder identification during diagnosis.
