Installing vehicle wiring harness
View Patent ↗One or more connectors at one end of a wire bundle are passed through a polarized through-opening in a wall. The wire bundle is advanced to place a grommet having a substantially right angle curved bend, through and along which the wire bundle curves, immediately proximate the polarized through-opening on one side of the wall. One end of the grommet is inserted into and through the through-opening, and the grommet is advanced to pass its curved bend through the through-opening until the curved bend is disposed on the other side of the wall. Then a polarized groove in the grommet is seated in the polarized through-opening to locate a direction in which the portion of the wire bundle exiting the one end of the grommet extends from the grommet's curved bend.
1. A method of installing a wiring harness in a motor vehicle that has an interior compartment, an exterior compartment adjacent the interior compartment, and a wall separating the two compartments from each other, the method comprising:
passing one or more connectors at one end of a wire bundle through a polarized through-opening in the wall in a direction from one compartment to the other, then advancing more of the wire bundle through the through-opening in the same direction until the wire bundle has been advanced sufficiently to place a grommet that has a substantially right angle curved bend, through and along which the wire bundle curves along a substantially right angle curved bend, immediately proximate the through-opening on one side of the wall, inserting one end of the grommet into and through the through-opening and then advancing the grommet further to pass its curved bend and the substantially right angle curved bend of the wire bundle through the through-opening until the substantially right angle curved bend of the grommet is disposed on the other side of the wall so as to direct the portion of the wire bundle exiting the one end of the grommet in the other compartment substantially at a right angle to the portion of the wire bundle exiting an opposite end of the grommet in the one compartment, and seating a polarized groove in the grommet in the polarized through-opening to locate a direction in which the portion of the wire bundle exiting the one end of the grommet extends from the curved bend of the grommet.
2. The method set forth in claim 1 comprising seating the polarized groove of the grommet in the polarized through-opening by pulling on a tab extending from the grommet's curved bend opposite the polarized through-opening.
