as long as you have an automatic, that hole works.
Just push the wire(s) a couple of inches through the seal from the engine compartment.
If you shine a flashlight from the engine bay at the hole after pushing the wire(s) through, you can see the location from under the dash.
I have 3 wires going through that place no problem.
