I could not see a way to get a picture from the engine compartment, the hole is just under and to the inside of the brake booster.
If you fold the top of the carpet down just under the brake pedal you will see a punch out in the sound deadener, Once you look there and reference the picture I sent you should get a good feel of where I found to pass wires through.
