Conversation Between microdevil45 and SpringerPop

Unfortunately, Ford doesn't release the internal schematics of their modules, just the interconnecting wiring. Nothing on the internals on the GEM, the PCM, etc.
There's a repair place that obviously has been able to get them, but they might have been "reversed engineered", too. Don't know.

Hello, first thanks for all the posts they have helped greatly. Also your website has me getting ready for all the extra filter installs. I do have a question for you. Do you have an electrical diagram for the GEM module? I have an extra one I want to test and if I can get a diagram for it I will set up the I/O for it and maybe even fix it. Thanks for everything.
