I haven't seen anything on the 460 but the walbro 400 im using was designed to use the stock pump controller or hard wire. I already had my stuff torn apart for the Bosch so I hard wired my walbro with 10g. I will say the car idles and cruises drastically better now that i switched pumps and added a thicker gauge power wire. So i never got to test the larger walbro with stock harness.
