Electrically the MS1 and MS2 chips are both 0-5v for all inputs and outputs.

There are different pins used for some of the inputs and outputs, which you may need to check, but the signals themselves are the same.

For 4cyl and 6cyl wasted spark the tach input and spark outputs are the unchanged.

Check the input/output wiring guide.
