I went through all of the steps involved in replacing the big clock with a used tach. Things seemed to go fine, the red and white wire went on the same spade it came off of and everything went back together smoothly. Enrything still works exactly the same, the speedo keeps speed, gas gage tells me how much fuel I have, the clock still doesn't work and neither does the tach. Do those 3 other spades do something or are they decoration? Anything else it might be?
