Bulkhead: passing cable through

Hello

I have posted this topic before so this repeat post is just in case...

2025 variant

I would like to pass a cable through the bulkhead. On the Yeti, the firewall cable bung had blank nipples to do this but I cannot find the same on the Karoq - as I cannot even find the bung if it exists.... The alternative would be a piggyback fuse holder at a suitable place on the internal fuse box. (20A max so the accessory socket fuse could be a good candidate - once I have got strong enough fingers to deal with the side of the glove box!)

Has anyone had experience of passing a cable through the firewall safely?

Thanks
