Has anyone checked into one of these from Ford Racing?
EFI harness (http://store.summitracing.com/partdetail.asp?Ntt=fms%2Dm12071c302&N=0&part=FMS%2DM12071C302&autoview=sku&Ntk=KeywordSearch)
Saw it in the summit catalog and was a little curious. Well, ok, maybe more than a little :grinno:
And that answers your question right there....ours is basically a modified Mustang EFI system. That harness you found is more for hot rodders, or for earlier non-Fox cars that never had SEFI.
