does anyone know the wiring diagram for a ls distributor system like the - and + from the coil wires goes to where? ? also anyone knows what is that brown looking resistor box that has 3 clips (i was told it is a ign. module, or a ballast resistor) ? i tried to google n search here in the forums but got nothing ... please any help is much appreciated... i tried to hook up the msd 6al n i have a feeling it is hooked up wrong cause there is a buzzing sound from the 6al!

 

brown is the ignition module...
and yes the msd has a humming noise to it is normal....
