1986F150Six Posted March 11, 2020 Share Posted March 11, 2020 Says for 1987 with 5.8L engine. Looks like Duraspark wiring harness except for one electrical connection. https://www.ebay.com/itm/NOS-1987-Ford-F150-250-350-Truck-Van-Dash-To-Engine-Wiring-Harness-E7TZ-14289-E/124068606088?hash=item1ce310b088:g:PzQAAOSw9MReNeAm Link to comment Share on other sites More sharing options...
