G'Day, I need to feed a thin cable thru the bulkhead and into the cabin to operate a relay which will be located near the battery. I've had a quick look for rubber grommets to pierce but found none.
Is there an easy way apart from drilling a hole? Car is a TL sedan. Thanks.

In behind the fuse box is a hole in the inner guard, this already has a harness, follow your cable up over this and in through the pre existing grommet in the a pillar, take off your inner spash guard to get up in there

It is illegal to cut inot the fire wall so this is the best way of doing the job properly

Excellent - thanks for the prompt reply.
