    At least on my '72 Ranchero GT, the instrument cluster has to be connected or it won't start. DAM! I hate when that happens.

    I hope you put the new circuit on , it was my understanding you had done the cluster already, yes you learned something all right, do not take everything apart do 1 project at a time especially
    when it involves electrical

    Now you know why some with GT clusters change over to the newer 3-wire clusters--to allow engine starting when the cluster is removed, and prevent shutdown if the tach fails.

    But that is a great circuit to wire a hidden kill switch into. ;)

    Yeah, it does. The tachs from, IIRC, '75, have to be inductive pickup because of the Duraspark ignition, or something like that.
