Just to make it interesting... the car I want to do this on is a 1975 Porsche 911.

They came stock with electronic ignition triggered by points. The original Bosch module seems to work, sometimes. An aftermarket unit that came with the car doesn't seem to work at all. The aftermarket unit costs over $400, I'm scared to price a Porsche one.

Some research on the net revealed that there was a class action lawsuit against Ford for defective ignition modules. If they reached a certain degree of heat they just quit dead on the hiway. When they cooled down away they went again. Thousands were stranded this way, Ford knew about it for years and did nothing about it.

So if you use the Ford module be sure to keep it cool. I don't know if they ever did fix this but I expect they did. The lawsuit was in 2002.

As to the location of the module. Most of them are right on the side of the distributor, in other words part of the distributor. Some are remote mounted on an aluminum heat sink on the rad support. So far we know Aerostar vans and T birds are that way.
