Yes mate. As you would be aware, there is very little access to the cabin from the engine bay.
It keeps the engine bay clear and clean of excess wiring. Looks more professional as well, as it can be hidden extremely well.
Access to the driver's side guard is right next to the battery and the wire is able to come out near the door hinges, then, behind where the door loom
comes out of the body to the door, there is a spare hole with a grommet in it.
This goes in behind the kick panel and it is just a matter of running the wire/s under the plastic door sill trim to the boot.
I passed it through the guard in 2 stages. From near the battery to the side indicator, then from there to the door hinges.
Just used a piece of coat hanger wire with a hook on the end for a pull through.
I have a manual and don't have the spare clutch grommet any way.
I did a 'How to' on it a while ago
https://forums.justcommodores.com.a...inside-car-vt-vx-may-work-other-models.210577 and originally passed the wire through the door wiring grommet, until someone pointed out the hole behind it.
I know some might say...."what if the guard has to come off"?
Well I'll cross that hurdle if and when I come to it.
Besides, I've used different coloured wire for different things so it's just a matter of matching, cutting and rejoining if necessary.
