Need help wiring up a dual on3 fuel system. I have the fuel hat and not sure what color wires I need to hook it to. I have the controller with the relays but want the pumps to cut on and off like the factory pump. Am I asking too much? I will be running a return style system so what’s the best way to wire it and does anyone have a diagram ? 2007 Mustang GT

How does that work??? How do you maintain fuel pressure with the pumps not running? I'm not sure you know what you're doing here. You might want to step away from the car and figure it out before you cut the fuel pumps off and on with a return system. The pumps need to be running constantly and normally at max voltage.

Pumps in a return system traditionally run at full speed all the time. I know of some exceptions where the pump is run on a 2-speed strategy (I assume based on MAF) but none that combine a return line and full PWM control.

Regardless of all that, you need to be asking the vendor.
