Can I run wires from the engine to the interior without drilling a hole?
Yes. Remove the ECM (computer) unit (the box with the metal fins) on the passenger side rear of the engine compartment, and swing it out of the way. Directly behind it, on the firewall, is a grommet with a 1.5 inch hole in it. Punch another hole in the grommet, and put your new wire through it. The wire exits inside the car in the corner of the passenger’s feet. Take off the side kick panel inside (which includes the molding on the bottom of the door jam) and you can access it.
