The deicer harness is located in the cowl area.
This may be caused by vehicles being equipped with an aftermarket windshield assembly with a poorly seated or damaged deicer harness. Water can enter through the deicer harness, wick down to the common shared ground junction A72 and then wick from the A72 ground connector to the inverter water pump connector.
