The fuel pump harness utilizes 14 gauge yellow/red and a black wire going to a six terminal Delphi GT 250 series connector. The connection is made between the fuel pump harness and the main wiring harness on the driver side of the engine at the rear of the cylinder head. The yellow/red and black wire are simply connected to the end users fuel pump using a simple butt splice and the circuit is controlled by the ECM through a 35 amp relay. The fuel pump is programmed to prime the fuel system at key on and it is turned on continuously as soon as the starter relay is triggered by the end users ignition switch. The fuel system prime feature ensures easy starting without the fuel pump being turned on continuously when the ignition switch is turned on. This is a great feature for hot rods and street vehicles that have loud or high amperage fuel pumps. If the end user needs the ignition switch on for lights, A/C fan, radio, or any other reason; the fuel pump will not run continuously.
Note: Fuel pump harness must be purchased separately from the Mast Motorsports control and performance packages
