'92 blazer ignition module

Okay out there, how do I change the ignition control module on a '92 Blazer 4WD 4.3 V6 TBI Engine? I've searched the forum and found nothing so far...So I thought I'd ask...

Unplug the wires at the distributor, remove dist cap. Remove rotor. remove both 7mm screws on module, lift out. Replace in reverse, put about a 1/4" layer of dialectric grease on the bottom of the new module. (Or you will be replacing the new module in a month due to heat damage)

thank you very much!! It worked!! Just so I would know though, how could you be able to tell if the coil went as opposed to the module?...
