1987 Honda Accord ignition module

Electrical problem
1987 Honda Accord 4 cyl Automatic

I was hoping you could tell me where the ignition module is located and how I can test it, what the specs are and how to remove and replace it.
I know my no start problem has something to do with the ignition system and I have already ruled out the ignition coil and wires as a problem, now all I need to check is the distributor cap and rotor and the module. But I have no Idea what the module looks like or anything.
I would appreciate your help! Thanks!
