Hi,

If those are inductive spiral monel = wires,=20 then they are required for the MSD to keep the electronics alive, and = on the=20 stock amplifiers probably won't hurt a thing, as those were run with = the=20 ghastly carbon dust wires.
 
Also needed if you want to hear = anything on=20 the radios.
 
Keep the MSD powered wires dressed = away from=20 ground and secondary wires for the trailing plugs. The excess energy = can burn=20 through even fat silicone wires.
 
I love my MSDs.
 
The MSD will fire the coil(s) once = when you=20 turn it on, and once when you turn it off.
 
This is not your Fathers ignition=20 system.  (The Kettering field collapse system)
