Message	that can be used for an additional ground to the second pump. I soldered a wire to this pin and haven't had any issues running two stock TT pumps, one on each side of the tank. the ground wire is what comes from the controller. For some strange reason, Nissan decided to modulate the pump output using ground instead of power. This is a PITA, because this prevents you just just grounding the pump to the bulkhead. SZ recommends using a hobbs switch setup which will work fine so long as you don't heavily track the car. in a track setup you either need an external surge tank setup if using a hobbs switch (requires a minimum of three pumps), or a pump on each side of the tank (requires two pumps)
