I don't have any other american car around to test my PCM, I live in Belgium and this project is for a 1981 Corvette

Yes, there are no sensor plugged.
Big red terminal of the harness to +12V BATTERY
Black wire terminals (2 of them) to GROUND
I provide +12V to B9 for IGNITION 0 and IGNITION 1
On the OBD2 side:
+12V from Battery on pin 16
data from Dark Green cable pin 58 PCM BLUE on pin 2
GROUND from battery on pin 4 and 5
All my positive feeds are fused by a 20A and there is no short circuit anymore
Nothing else
