This is an excellent reproduction of the rubber grommet for the wiring that comes from the wiper motor through the firewall. The grommet was made just as the factory Nissan grommets came, in a closed circle. In order to get the wiring through the grommet, you will need to take the wiring plug from the wiper motor, carefully back out the wires from the plug itself, pass the wires through the center hole, then replace the wires into the plug (be sure to mark them before removing them). One could also cut a radial slice into the grommet and then use a rubber sealant (see Related Items below) to hold it together, but the first method is recommended. Please call if you have any questions. See Related Items below for installation lubricant.
