Today I messed with the connection, got the tach to work. However, once the dash lights come on the reading on the guages drop all the way down and the turn signal and highbeam lights are illuminated. I plugged the old cluster in and it was fine. I'm gonna look for another cluster. Although it was fine yesterday except for the tach, my thoughts are there is a bad connection on this cluster. Thanks for all the input guys.
