Red/yellow/blue from ignition module goes to coil. I think blue is front cyl, yellow is rear cyl, and red is power to coil.

Tach signal comes from green wire on ignition module.

If you are wiring in a PDM kit you have to use the existing wire that goes from the ignition to the coil. It is not supplied with the kit.

Check the continuity from green wire at ignition module to the speedo connector yellow wire. Green wire at speedo should be for neutral light. If everything is wired up correctly then you might need to take apart the speedo and look at the circuit board. Do a search on here, it is a known problem that sometimes the wires break where they are soldered on the circuit board in the speedo/tach.
