B8 - MAP input (AV2)
B9 MAP 5V
B19 MAP 0V

B10 Sync 0V
B11 Ref 0V

Hi Ross, the heat from external wastegate accidentally burn off the wiring harness. The heat insulator was burnt off.
We've managed to fix the wiring but we couldn't find the right wiring pattern for some outputs and inputs.
Could you kindly advise which pin for:
Outputs: Fuel pump, Electric fans and Idle motor.
Inputs: Aircond request, speed and anti lag request.

Thank you for your kind attention.
