Looking for FM4 Electronics Module

[Fromundr]

I am trying to locate an electronics module for my FM4, spoke with both my local dealer and Fuelmaker, neither one will sell me the part with out installing the unit. I do not want to install unit and need to find the part. Anybody have any leads as to where I might find this part without having to pay for them to come out and install this unit? Any help would be greatly appreciated.

Thanks
