The E9X/ E8X coolant tank level sensor extension harness is the same great product that comes standard with our E9X/ E8X relocated inlet kits. 

The coolant tank level sensor extension harness is perfect for those running a relocated coolant reservoir tank or 335D coolant reservoir. This harness plugs right into the factory connector allowing you to extend the position of the sensor without the need to splice any wires.
