module in distributor- what is it, how to remove it?

[Nerfdude]

my problem seems to be stemming from the module in the distributor that you plug a harness into from the side.... if you've read my previous posts, you'll know that i have a porblem where the car sometimes just won't start. it's manifested in a few ways. but i can replicate the problem by unplugging this harness, which leads me to believe that it's the problem. does anyone know what it's called and/or if it's removable? do i need a whole new distributor? thanks...
