Hey guys I got my hands on a MSD 6AL, and I'd like to put it on my car (run a MSD 6A now) this box was installed on my Coupe when I bought it but the car is bone stock...
I just wanna make sure it works.
 
Check MSD's website they may have directions for you. With it installed on the car there is a way to check to see if it's putting out power by jumping one of the wires to ground and looking for spark there. Pretty easy if you know which wire.
 
I was in the same boat when i got mine. I just deciede to hook it up and see what hapens. I found out the hard way that it was working. I use to beable to pull one of the plug wires off of the dis and really never get shocked. well after my 6al i got the crap shocked out of me and my arm was numb.
