1987-93 Ford Spark Plug Wire Routing Diagram - V8 Valve Cover Separators

This document is a factory-style illustration page covering 1987-93 vehicles, showing the correct routing of the spark plug ignition wires over the left-hand and right-hand rocker arm (valve) covers of a V8 engine. The top diagram shows the left-hand spark plug wiring assembly (part designation -12281-) routed across the L.H. rocker arm cover with cylinders #5, #6, #7, and #8, using a T-stud and wire separators to hold the wires in place. A note highlights that the #7 spark plug boot and wire seal area (circled in the drawing) must maintain 3/4 inch clearance to the oil level indicator (dipstick) tube and bracket. The bottom diagram shows the right-hand spark plug wiring assembly (part designation -12280-) routed across the R.H. rocker arm cover with cylinders #1, #2, #3, and #4, again retained by separators and a T-stud, with 'VIEW A' and 'FRONT OF ENGINE' orientation arrows. The drawing carries reference number 94A52225. A reader can use this page to correctly route and secure spark plug wires by cylinder number and to verify separator/T-stud placement on both banks.
