Hung Like a Stang

okay, so after all this shti that happend to me last night i have yet one more problem.

Whenever my MSD box is plugged in (with the special wiring harness) it like, instantaneously drains my battery, and the car will not start. However, the car runs fine if its jumped to start with the MSD plugged in. Also, after I get it running, if i shut it off, start without the msd box, it starts and runs. I am going to get my battery tested just to rule that out.

I have the box powered from my solenoid, stock coil is on it right now.

Any ideas?
