i hate import cars

Like it says, I need the diagram for the dash wiring, specifically the cluster, for a 1995 Civic DX hatch. Anyone know where I could find it? I searched on here but all I found was one for a cruise control switch.

Or maybe you guys might have an idea what's going on here. I have a 1995 DX with an EX cluster w/ tach in it. The center backlight bulb at the top flickers on and off with bumps and whatnot, and when VTEC engages, the speedometer jumps up a lot, sort of flickers I guess. It always goes up, never falling below the speed I'm actually going, and it's only when VTEC is engaged.

What I'm hoping is that there is a common ground for these that may be loose or something, and I can fix it all in one shot. But that's why I need the diagram because I can't afford to have th car down for long. So I need to try and track it down BEFORE I tear into it. Any thoughts?
