I'm pretty baffled by this and maybe someone here has had some sort of experience with it. I have an aftermarket Tach+light in my car, have it had installed for a while now. Recently, it has been flickering on and off by itself. Now if that wasn't wierd enough ,it seems to be doing this everytime I push down on the clutch a certain way. Now I'm thinking it's a loose wire somewhere, maybe grounding out...but why does my damn clutch pedal control if it goes out or not. I'm sure I will just have to go and start checking wires, but if anyone knows what the hell this is it would be greatly appreciated.

 

check by the clutch linkage to see if a wire is chafing on it. that might cause your problem.
