G5 Voodoo Pro V1 Pinouts

Notes for wiring

Power

• Pin A5 is the main ECU power input. It can be supplied with either switched or constant VBat.

• Pin A6 is the ignition switch input. It must be connected to a switched battery source. The ECU will not power down if A6 is connected to constant VBat.

• Pin B5 needs to be supplied VBat from an external relay to power the H-Bridge drivers (AUX9/10/HB1 and AUX11/12/HB2). These drives will not function if B5 is unpowered.

Grounding

Grounding of the ECU should always be done to a single common point on the engine block or heads to reduce any voltage potentials between sensors and ECU grounds, and prevent ground loops.
Failure to ground the ecu to the engine can introduce inaccuracies in sensor readings.

• For any sensors with a ground pin on the sensor, only ground these to shield or sensor grounds on the ECU.

• Ensure the engine is well grounded to battery negative.
