Help Installing a 68 gt tach
Help!! I'm going to reinstall the original Tach dash back into my 68 GT S Code. Someone else restored it and used the standard harness's along with a standard dash with a small tach where the clock should be. The signal is on the - minus side of an MSD blaster coil. I'd like to do the easiest solution. I'd keep the existing harness. I've figured how to connect everything but the stock Tach. I'd like to connect one wire to the ignition (Constant voltage unit) and the other wire (red) to the + side of the coil using a ballast (1.5 ohm) in between. It seem to me that the Tach can be wired separately. Will this setup work, or I'm I all wet about this. I've be tring to find a Tach schematic with no luck.
