Let me get this straight, you wired the unit up by running a wire directly from the battery to the MSD box?

If this is the case, you need to disconnect the wire at the battery and run it over to a wire that only has 12v when the key is turned on. That will solve your problem.

Sounds like you got it wired correctly, but it's pulling power anyhow. Odd. Have you checked MSD's website for people with problems like your's? You did run your ground wire straight from MSD to the battery also, correct?

Ok, didn't realize they a switched AND a non-switched power wire for that thing. Any chance you got them mixed up when you wired it up?
