Default Ignition Coil Wiring

I am replacing the harness to the two ignition coils and power amplifier modules. Does anyone know what the harness name is and part number that goes to the ignition coils. Are the power amplifier modules on top of metal plate at the front of the car still being used and is there a harness and what is the number? The some of the wires in the coil connectors have broken off and falling out (attached pictures). What type of connectors are used for the coils? Can you get new connectors for the power amplifiers? What is the part number?

I think Barratts had the amplifier plug. Make the coil cables yourself.
