Hey all, does anyone know how I could get a switched/ignition LIVE through the firewall into the engine bay on my 2016 RRS? I don't want to drill new holes etc. Is there are existing grommet etc? Any help much appreciated.

Surely there's 1 or 2 there already

Normally there is a big grommet for the main body to engine bay harness and there’s a small nipple for repair wires to pass through if required. 2012 5.0 SC AB
