my tac needle keeps bouncing up and down, but it will work as soon as i push the dash in. im thinking there is a wire loose or something. and does anybody have a link to a write up on how to take my gauge cluster out. thanks.

 

I know it's a solid blue wire that runs from the dizzy all the way to the cluster. Find it, and make sure it's tight.

 

You got two screws under the black molding where the hazard and dimmer and two more on the back of the cover. Take those out and lift of the cover. Unplug the switches and dimmer, and you got access to the cluster. The gray plug on your left has a blue wire on the far (left?) edge. Thats the tach signal.

 

thanks both oh u
