I'm trying to figure out how i can access th firewall to run my power wire through. I've read that there is a rubber grommet below the battery which in my RHD cx5 comes out near the passenger footwell, the problem is there is an fan unit blocking access to the rubber grommet and it looks near impossible to remove. So i'm really out of options? it seems like drilling a hole will be the only way in RHD cx5's.
