sorry to have another post about my tach but i need to get this s*** worked out. Ok i went to the shop today and he was going to install it, i had the diagram and everything he needed because i finally figured out i need a adapter. He said he needs to connect it to the pink positive(+) coil, but there are three diffrent ones. Whoever installed their autometer tach and shiftlight, please let me know which wire, or can u send me the schematic for the ignition system (thats what he said he needed, or the best would be just to know which wire). I asked him to show me and their were like three coils of wires on top of each other and if you could just tell me which would i would really appreciate it.
