So i have removed the MSD system that was installed on the car with the rev. converter and now the tach no longer works. I am going to remove the dash board and i though i would trace down the wires and hook the tach back up. Can somone please tell me what the 3 wire that come out of the tack go to so i can confirm where they go and what needs to be fixed when i do this modification. Thank you for your time

What wire did the output of the tach converter go to?
