There are various hoses and wiring bundles going through it, but from the inside I don't see a clear path next to an existing hose or bundle that the wiring can be worked through. I was hoping to find a removable rubber grommet but don't see one. I suppose that's a testament to the builders.
Have you run wiring though the firewall from inside the driver's area without having to drill a hole somewhere or did you find an opening large enough to accommodate three small wires? Where?
Behind the battery there is a grommet. Remove the battery and tray and expose the grommet, there is a nipple on the grommet that can be cut off. This exposes a hole in the grommet that a wire can be past through.
I have heard of access in the fuse box area, this may through the hole the fuse box harness goes through, not sure though.
