EDIT: After rereading your post, do you need the engine gauge feed harness? That's the one that goes on top of the engine for the gauge and ignition coil feed.
The one I posted is the main harness that goes around the splash pans and up under the dash.
The engine gauge feed wiring harness (14289) plugs into the dash panel to engine wiring harness (14398) which then plugs into the main dash harness (14401).
1978 LTD II/Ranchero: There are EIGHT possible engine gauge feed wiring harnesses!
A.T.C. = Automatic Temperature Control.
Sold new in CA vehicle: The DSO code stamped on the Warranty Plate will be 71 or 72.
