It just died one day, I came home at night the car worked perfectly and next morning I went start the car and it didn't start, anyone have an idea what could go broken from the box?
Does anyone have the msd 6al box wiring diagram or does anyone know where(web) to find one?

 

Try this:

Bypass the box and see if it runs. You can always send the box to MSD for repair, if needed.

 

I unplugged the box from the car and the car started and worked fine.
Thanks guys.

 

This page didn't help me... but thanks anyway

 

The link I provided gets you to a page that has the basic MSD 6AL instructions plus additional information about wiring the 6AL in a variety of unique applications. If you click on the basic 6AL instructions link it will download a 2.2 MB .pdf file which is what you were asking for.

This link will get you there directly:
