Rear Hatch Wire and Grommet Identification - Three Grommet Layout

ElectricalbeginnerCommunity Verified
Problem

Owner needed to identify the wires and grommets routed through the rear hatch before removing it, unsure which grommet carried which wire/hose.

Unable to identify rear hatch wiring at grommetsUncertainty about which grommet carries antenna cable vs wiper harness vs washer hoseNeed to disconnect wiring before rear hatch removal
Root Cause

The rear hatch has three grommets that are not obviously labeled, and their routing is not immediately apparent, especially on dark-colored cars where the smaller center grommet is easy to miss.
