Installation Notes:
When selecting solenoid configuration in the Holley EFI software, use the Dual Holley drop down selection. It is not advised to use the PWM+ outputs on an HP ECU, but rather use the PWM- Outputs. If you have a Dominator ECU, either use the PWM- outputs, or use a PWM+ output on the J2B connector.
