My tach adapters are apparently not the right ones for the duratec application, or they are faulty because the car won't crank with the tach adapers wired in. I didn't have time to fool with it much this weekend, but I'll have to pull out the tach adapters and send them back to MSD for testing....or they may just give me some different ones to try. Anyways, thanks for the interest and I'll be sure to post any new info as soon as I find out.
