I working on the mother of all wiring harnesses for my EFI conversion and I ran across this thing during my travels.

It is a PDM designed for motorcycles and UTVs to minimize wiring when adding accessories like lights and stereos. Same principle as the PDMs from Motec and Racepak just smaller and more affordable.
Anyway, when you create an EFI harness you have to have some circuits outside of the ECU to power the ECU itself and higher load items like fuel pumps and injector drivers that the ECU can't drive. Do you think this little black box could do the job rather than wiring in and extra fuel panel and relays for those circuits?
The outputs are configurable through software and you can adjust the amp loads and trigger settings too.
