Facelift Wiring through firewall

[Golfather]

Planning to retrofit front parking sensors to a 8V
What is the preferred method to route wiring from the bumper to inside the cabin?

Options Ive seen is behind the battery through the firewall grommet, or from drivers side.

Any retrofit guides out there please?

Thanks in advance

Maybe the below installation guides for JB4 can help you.
