How to get a wire into the cabin through firewall
Hi All;
Trying to get a wire through the firewall into the cabin for front parking sensors/camera.
I own a 2006 cls500 w219, and I occasionally post to this forum because my car is essentially the same chassis as the w211.
On my previous car, a c230 w203, there was a big hole in the engine fuse box I could probe a wire into the cabin, but no such luck on my w219.
However, there seems to be a grommet with wires going into the cabin behind/under the fuse box.
Can anyone confirm that these wires go into the cabin (ie, through the driver's side interior fuse box)?
Any other suggestions on how to run the wire?
Thank you very much in advance!

sneaky way to get wire into cabin
Look closely at the bottom right hand corner of the windshield. See the yellow dotted line along the trim, where the two metal panels are adjoined. You can stick a wire in there from the engine compartment and it will go into the cabin. No need to mess with firewall!
Figured out how to run the wire, didn't have to go through the firewall.
Just poked my fingers through the trim with the engine hood open into the cabin.
Wires tucked away between adjoined panels.
Yellow dots show pathway of wire, easy peasy!
