Hole in the firewall on the passenger side?

[zZsKyZz]

Does anyone know of a hole I can use on the passenger side of my mustang so I can put the wire and hoses from my ZEX box to the engine compartment? I'd really like to hide that box somewhere...

Does anyone know of a better spot to hide it? I'd love to put/keep it in the glovebox or somewhere near the passengers feet... any ideas/pics?

Thanks

if you take the wheel off then tak off the wheel liner you should see where the wiring harness goes through the firewall put through that grommet.

theres a little drain for the a/c that goes thru the firewall on the passenger side you could use.

i ran my MSD box wires through there and have the box in the glove comparment

I ran my wideband through this same grommet - comes out in the perfect spot right above the glovebox.
