Haltech FD coolant level beep and light
i dont know if this is the best way. but i think i shaved off the insulation around (i think it was) a brown wire (not to sure about the color, look it up in the wiring manual) up in one of the 2 grey conectors (driver side) near the battery, and grounded it.
the coolant acts as a ground and since i did away with the sensor, this was an easy fix for the buzzer.
