Check out the sweet gauge bezel TTS sells for customers who don't already have an EGT gauge. Essentially this bezel replaces the passenger airbag control switch on the dash just to the right of the HVAC controls. The airbag control switch is relocated to the glove compartment and remains functional. We like this arrangement because it requires no drilling. Simply snap it in place and wire up the gauge. We selected a sweet digital Nordskog EGT gauge for the project.
