Just to try and help any way i can.

The VSS signal on '90's Ford is 132 Hz @ 60 MPH
voltage 1.5 to 5.5
resistance 190 to 240 ohms

the injector fires every 2 engine revolutions, grounded by the EEC(Ford)
so injector pulse X 2 is rev's

the injector pulse varies from idle @ 3ms.(car)
to 17ms.(truck) @ 55MPH
resistance 11 to 18 ohms

does not include throttle body injection,
peak hold injection,or
early flex fuel with extra cold start injector.
