Passing through the interconnecting cable to the interior.
Pass the interconnecting cable through existing holes in the inner fender or via the A-pil-
lar into the interior of the car. The plastic inner fender must be removed. Remember to
pass through the 5-lead cable for the control unit.
Be careful if it is necessary to drill a hole to pass through the DEFA
Plug-In cable from the engine compartment to the interior. Do not
drill in double plating or reinforcements.
The DEFA Ø20mm hole saw is a particularly suitable tool for this
task. Make sure that the tool does not damage fitted components,
brake lines, electrical cables etc. For the rust-proofing warranty to
be valid, scratches and cuts in the paint must be repaired with a ma-
terial approved by the vehicles manufacturer.
Use the enclosed rubber bushing to seal the hole. Make sure the
rubber bushing is fitted properly as it may otherwise be a conduit
for water seepage into the passenger compartment. DEFA Plug-In
cables should slope downwards from the passing through point in-
to the engine compartment (1) so that water or humidity does not
run along the cable into the car interior (2).
When drilling a hole in the engine compartment wall, care must be taken so
the tool does not damage fitted components, brake lines, electrical cables etc.
Installation of the interior heater.
Install the interior heater and its plug in a suitable location in the passenger compartment.
Use the enclosed mounting bracket to mount the heater.
The interior heater can be installed in the following positions:
Upside-down, e.g. under the glove compartment; on the side wall, e.g. on the middle con-
sole or the A-pillar. The airflow must not be directed downwards. The interior heater
must be mounted so as to satisfy the requirements for free space around the heater. The
requirements are shown in the sketches below.
