This is the coil pack off my 90 awd. Do the 1990's have a 4 pin plug or is that 91-94?

The testing procedure is no different from the 3-pin coil (shown in the diagram). Simply ignore the white wire.

1990 Coil
Pin 1 - Yellow w/ black
Pin 2 - Yellow w/ green
Pin 3 - White
Pin 4 - Black w/ white

1991+ Coil
Pin 1 - Yellow w/ black
Pin 2 - Yellow w/ green
Pin 3 - Black w/ white
