Need help nothing works!

Yesterday I installed an Autometer Sport Comp mechanical boost gauge in my 99 GSX. I did not get the back-lighting for it so there was no wiring to be done. After we got it onto the A-pillar I turned on the car and half of the stuff electrical in my car does not work. The ABS, head unit, rear-view mirror lights, trunk light, floor lights, and the key FAB doesn't work. I didn't touch any wires, although I had to route the vacuum line right through all of the electricals near the clutch assembly of my car. I routed it like like most people do it; through the dash at the A-pillar, through the steering wheel column rubber boot, and tapped in to the intake manifold to FPR vacuum line. On top of this the gauge barely works. At full boost it gets up to about 4 psi, an I know I'm running wore than that. Can someone please help me? I just replaced my clutch master cylinder and don't want to have to bring it to the shop again.

Check your fuses.

Would one fuse correspond to all of those things?

Did you disconnect your negative battery terminal before you began working? This is always an important 'must' before doing ANY work with electrical. I've been talented enough to blow multiple fuses, installing new gauges. Check your grounding wires and make sure that they are secured tightly to a good unpainted grounding point.

As for your gauge not functioning correctly, it sounds to me like you're either losing pressure along your vacuum lines, or your gauge itself may be malfunctioning.

I did not disconnect my battery cause I wasn't doing any wiring. Usually I do and I guess I should have. I still haven't check my fuses yet but as soon as I do I'll give you guys an update.

Check the BIG ones under the hood-

So the big square ones?

Sorry for all of the stupid questions but I'm not that good or familiar with electrical systems. Do I need to take out the fuses to check them? I do know what a blown one looks like, sort of.

Just thought I'd put up an update. I fixed my problem and it was a blown fuse. It was only one fuse, actually. I don't know how the stereo fuse caused my anti-lock brakes to fail but it all works now.
