Grommet feed-through knob
Grommets are a component of the main wiring harness, which contains securely tied bundles of cables. It is not possible to feed additional
cables through with the wire bundle. Grommets have a feed-through knob moulded into the grommet where an additional hole can be
made using the following procedure:

Make sure that the immediate vicinity is clear of obstructions and/or components, in order to avoid damaging critical systems.
Use a suitable tool, such as a knife or diagonal cutter.
Cut or shorten the outer end of the feed-through knob.
Feed the electrical wiring through the grommet as required.
Apply sealant as needed to ensure air-tightness.
Information
-
The maximum diameter of the additional wire
bundle is 8 mm.

There are two locations in the dash panel for
additional holes to feed wires through.
Practical note
–
Electrical wiring harnesses that pass through sheet
metal must be fed through protective grommets,
which also ensure a watertight seal. A windscreen
sealant or silicone sealant should be used. Adhesive
and tape are not acceptable.
–
The grommet feed-through must be adequately sealed
to prevent corrosion and water ingress.
