I am a little confused. A 73 didn't have a module, it had points. If it has a module in it then it must have been modified. If so, you need to post a picture of it so that we can see what it is before we can help you. Am I wrong here?

Like the diagram, nice and clear. I have six or seven of them.
dipstick66: If I recall correctly, solid state ignition didn't come out till 74. Here is a diagram for that one. See what color the strain relief is on the control module.

1974/79 DuraSpark Electronic Ignition
NOTE: The module used in 1974 is 1974 only (D4AZ-12A199-C) / The module used in 1975 is 1975 only (D5AZ-12A199-C).
1976/79: There are three different modules, one was only used with specific sold new in 1977/79 CA vehicles (Edit: has a red plastic square).
Look on the module above where the wires feed out, there is a colored plastic square used to ID them.
Motorcraft modules have ID numbers cast into the housing. 1974 examples: D4AE-12A199-A1A, or A1D, or A2C, or A2D.
Most common 1976/79 (also used well into the 1990's) DuraSpark Ignition Module:
1U2Z-12A199-AA (replaced D9VZ-12A199-A, D8VZ-12A199-A & D6AZ-12A199-A) .. Ignition Module BLUE plastic square (Motorcraft DY-893) / Available from Ford.
There's also this little charmer:
D4PZ-12A112-A .. Stator aka magnetic pickup coil (Motorcraft DU-1A) / Available from Ford.
Applications: ALL 1974/79 FoMoCo vehicles with DuraSpark & V8 engines except 1979 LTD/Grand Marquis 351W with EEC.
DuraSpark intro'd in 1974, but not all vehicles had it until 1976 as it depended on the applications.

While searching for a good pic, I ran across one with blue instead of purple and one with a red replacing the orange so I don't doubt you. I'd follow the pinouts on connecting plugs. May be an aftermarket distributor thing.
