Boost gauge in. I had some little scrap pieces of the gold tape left over from wrapping my intake and noted the heater in the TT is quite strong so I threw some on the back of the vent gauge for some extra piece of mind. I wired it to an ignition activated 12V fuse. The gauge was designed to look like oem so I wired it up to the stock dash dimmer and the brightness matches whatever the cluster is doing.
