Ooops Re: MSD Box Installation



Re-reading you message, I realize that I may be very mistaken.  I'm used to 
MSD's digital ignition controllers, so I didn't notice that you are still 
using your stock ignition as well as the MSD box.  The green wire and the 
black wire that doesn't get power from the ignition switch should go to the 
MSD box. As for the other two, I would assume that the other black wire 
(whose job is to supply power to the ignition control unit, apparently) 
should probably be joined to the first black wire at the input side of the 
MSD box.  That's my guess, anyway.

The red/black wire might be your problem.  On an 8v, that wire goes to the 
idle boost control unit.  Maybe the boost valve is staying closed because 
this is a bad connection or something.  Just guessing.  Maybe that's why 
your car dies right after it starts?  Look for a bad connection in that 
line, and if that doesn't work, try switching it to the coil instead of the 
MSD input side.

Sincerely, and hopefully more accurate this time;
Brian Haygood
