My understanding is you cannot disconnect any of the 4 pins because the new single pump needs everything for power. The purpose of pulling the pin from the ECM connector is to prevent it from sending a shutoff signal intended for the second pump.

Haibeck's site notes that removing that pin doesn't impede the dual pump setup either. It just means the secondary pump runs full time since the ECM can no longer tell it to stop running.

I am not keen on modifying the original connector, so I am trying to find a male and female end to create my own custom extension cord that I can modify worry free, but my initial search hasn't been fruitful.
