I hate wiring.
I have a greddy EGT and fuel pressure gauge, and today I decided to finally wire the thing together.
It requires a 12v source, ignition hookup, illumination hookup, and ground.
The 12v is hooked up to the cigarette lighter fuse, the illumination to, surprise, the lights fuse (as referenced off projectwrx.com), the ignition to the ignition fuse, being the one next to the illumination fuse as far as I can tell. Ground is attached to the hood latch bolt.
After hooking everything up, The gauge works, until I turn on the lights. When I turn the lights on, it cuts the gauge out. No sign of illumination on the gauge either. If I unhook the illumination wire, it doesnt work at all.
What's goin on with this thing? Any help? Anyone?
