New tachometer, still nothing

[Delorean17@xxxx]

Hello List,
I just finished taking everything out of my interior. Now I just have a 
fiberglass underbody:) heres the story. when you turn the key the tach 
would go up as far as it could into the red line.(when you take the key out 
it rest at 6000 RPMS) I sent a post to the DML last month and most suggested 
that it was broken. I very kind member on the DML gave me a used tachometer 
that was in nice shape. I put it in today and received no movement from it 
at all. I then put in the old tach and it still went to the redline area 
when the key was turned. even if you move the needle backwards it will go 
counter clockwise into the red line area. Its like a magnet to the redline 
area......
what could be my problem? The tach he gave me worked when he took it 
out. could something else be the problem? Joe, any suggestions?

I see 3 wires on the right side of the gas peddle and they are clipped 
onto a plastic piece. I have one green one just hanging there. does anyone 
know what this is for?

Please let me know

Thanks

David
