yr ford engine is all old school
should have 1 wire for
oil pressure switch for dash
and a temp sender for the temp gaiuge in the dash
just find these sensors and replace them with the vdo ones
then trace the wires back to the inside of the car
none will goto the engine ecu
just dont confuse the engine coolant temp sender witht he gauge temp sneder
the gauge is one wire
coolant temp is 2 wire
