Ok I got the fuel pressure and boost gauge most of the way hooked up. I have a little problem though. Does anyone know which fuse I can run the pos wire so that the fuel and boost pressure gauges come on when I turn my headlight switch on???
By the looks of it, you should be able to jump off the brown 16 ga wire coming from the headlight switch. That is the lead that should get hot when your parking lights/dash lights come on. Be sure to ground the gauges well, and everything should be fine.
