First year the 351W was available in F150/350's: 1981. Never offered in F100's.

1976/79 FoMoCo vehicles: There are three different ignition modules, 2 were only used in some sold new in CA vehicles.

Modules have a colored plastic square above where the wires feed out used to ID them.

Blue: Some CA vehicles, all 49 state vehicles / Red & Brown: CA vehicles only.
