Question Denso ECU B6MU pinout

My Miata (Mazda MX-5 NB (2000) 1.6l 110PS) had a problem with maintenance. The car stood in the rain and because the spillover things in the back were not cleaned the water flushed in the car. Car still runs fine, but the motor indicator lamp in the dashboard lit up (which makes me curious). Been to the workshop - they tried to find the error-code but none was saved so they had a look on the ECU and stated its fried condition. Buyed a used ECU/immobilizer/locks set and replaced the old parts. When detaching the connectors to the ECU a I saw a loose cable (blue/red) hanging around from a of the three connectors. Since not all connector slots are occupied, its hard to figure out where it should go to.

Searched the workshop manual, google and the forum for my ECU (B6NA/B6MU) but no promising results (except this - but the pinout isn't available anymore). Since I don't want to reattach the battery cables in this state I was hoping to get some information/pics of your ECUs or maybe even a complete pinout. I even disassembled the ECU and had a look on the pins to figure out where it might go to when I stepped across your forum and wanted to give it a try - maybe you can save my silver hirame.

Long story short: Any pinout or pictures of your B6NA/B6NA ECUs are welcomed.

Additional information:
Denso 279700 - 1242 B6MU (waterdamaged)
Denso 279700 - 2100 B6NA (replacement part)
