A method for cooling electronic components comprising drawing air into a chassis; causing the air to come in contact with a corrugated deflector; and cooling electronic components with the air before the air exits the chassis. The invention also relates to a fuel injection device for carrying out the method. The fastener elements arranged and constructed to engage mating fastener elements associated with a supporting surface to selectively secure the cable to the supporting surface. The audio indicator has a receiver that receives the alert signal from the transmitter, and a speaker which emits an auditory response of the alert signal. The interconnect lines 408a and 408b are configured to be electrically coupled to the shielding film 416. In some embodiments, the alignment pin includes a hollowed head section for engaging a diaphragm slot in the turbomachine.
