#4403, "RE: Tips on installing Boost gauge?" In response to In response to 4
get a T-Tap from an auto store or pet store. Pet store sells metal ones incase you wanted a metal one instaed of plastic. Then just connect the vaccum line and split it and then run that hose back through the firewall through the steering boot column or the fender. Hook it up to the gauge. Then wire up the gauge ilghts by connecting to the parking lots. So when you turn your parking lights on your gauge will come on. Then you will need to ground it. Just find any screw that is touching metal and put it between the screw and metal (chasis of the car) and th en you'll be set. Hope all this helps. It's raelly not that hard.
