DeatschWerks C105 Dual Speed Brushless Fuel Pump Controller - DW650iL

The DeatschWerks C105 is the dual speed controller that drives the DW650iL brushless in-line fuel pump. It holds the pump at 55% duty cycle for low speed cruising and steps to 100% duty cycle when the white signal wire is switched to ground, so fuel delivery follows demand instead of running wide open at all times. Input range is 8 to 26 volts DC with a 40 amp maximum, and digital thermal protection shuts the unit down at 105°C to protect the electronics. A 36 inch silicone insulated harness and a bulkhead wiring kit are included for retrofitting into a pump module, and the controller is ethanol compatible.
