Front End
(Walk-in Van)
Manufacturers should minimize the number of separate wires and cables passing through the cowl panel from engine compartment to the cab. Wires and cables should be bundled and molded grommets or sealant on the bundles should be used where they pass through the cowl panel. (See Figure) The same approach applies to wires passing through the front radius cap for clearance lights. Also, when possible, connections between engine compartment wire harnesses and cab interior harnesses should be made using a sealed, surface mount connector on the cowl panel. (See Fig 1)
