I have no idea what you are talking about here. There is not 12 volts negative anyplace on your truck.
The Ignition Switch puts 12 volts positive on the BATT side of the coil. Power flows through the coil windings and out the TACH side and is grounded by the TFI Module when it sees a PIP pulse and delays the grounding with information from the SPOUT. The TACH side sometimes has a (-) on it but this just meant it went to ground.
You may also want to burn the Haynes manual when you are done an get a good Ford Manual for your truck.
