Re: Voltmeter wiring: would this work?
You aren't stirring up trouble. Trouble is when we get to 59 posts and installation of an ignition switch is still not complete because information must be dragged out bit by bit. If there are no dangling wires from the control box, you have two choices in my view. 1) Using a test light or voltmeter, check for +12 volts and ground at the engine end of the wires in the various harnesses. When you find them, open the harness sheath and make a splice at the control box end of that cable. or 2) Simply run a pair of wires from the engine bay or battery to the separate switch (momentary or SPST). On the other hand, if there are dangling wires from the control box, those were intended to power gauges and they will have a +12 volt and ground lead with the +12 volt lead being active only when the key is on. If the control box has a three terminal plug below the key switch, that's a tach connection and it too has +12 volt and ground connections as well as the tach sense signal.
