Alright guys. I installed my MSD 6A box, HEI, Blaster 2 coil, and MSD wires (along with some other things) this weekend. The whole setup is great, I couldn't be happier, except for one problem. When I turn the ignition switch off, the truck continues to run. I'm pretty sure I've got everything hooked up right. I followed MSD's own book for the wire hookups.

Purple & Green--Magnetic pickup
Small Red wire--Switched 12v
Orange & Black--Coil positive and Negative
Large Red Wire-- Bat. Positive
Large Black Wire-- Bat. Negative
White-- Not used

Now, the only problem I can think of is that the Small Red Wire has constant power. But it doesn't. It's the same wire I ran to my Pertronix setup. I unhooked it and checked, just to be sure, and it is switched. I'm at work right now, just trying to get some ideas on how to fix this. Any help is great. I'm going to go back and triple check the wiring later. Thanks. John
