ok i have another uneducated question.

an msd ignetion replaces the ignetion module right?

 

yep.

 

No, not exactly. In some applications, the MSD can completely replace the ignition 'igniter' module. But, in cases such as a Mustang, it can't replace the module, it simply goes between the coil the the module, leaving the module in place and functional.
