Depending on where you are going with the wires (to the passenger footwell or the dash area), I like to bring wires in through the fuse box (on the driver's side of the engine compartment) or through the box (next to the battery) with the ECU/body control module (and K40). Both of these boxes have large opening directly into the cabin and multiple choices for where you and bring the wires (from the engine compartment side) into them.

Cheers,
Chris
