When I did the conversion on my cart the 4 pin module I bought wouldn't work. It wasn't that the module was defective, it just wouldn't work for the HEI conversion. It was a BWD CBE4 (new version).

This attached pdf file by L. Dudzik gives information on how to test a 4 pin module to determine which "family" it falls within.

The module that worked for me was in the 1.25 volt family. I ended up using an Autozone DR100.

The CBE4 that I tried that didn't work was in the 0.0 Volt family.

Hope this information helps.
