Tachs usually have four wires.
1. Ground
2. +12 volt power
3. + 12 used for the light
4. Tach input from the pink wire on the coil

The turn signal module takes an input from the speedo. A new speedo would be required to use the module. It measures speed and distance to determine when to turn the signals off. It also only works with reqular bulbs, an adapter is required to use led's or small marker lights.
