I turn off the key but the engine keeps running.
This is a new problem after adding the MSD. Key turns off the power, I know, because I can hear the fuel pump turn off. It eventually shuts off after turning the key off/on/off/on or revving the motor with the key off. What should I do? Performance is spectacular, except gremlins are tenants.

Joe, the purple/black wire is the tach wire. It now needs to come off the MSD box and go to the tach directly.
The tach wire in the dash is a better looking prurple/black due to it's being protected from the elements for so long. For my fuel pump key on power I'm using a wire off the stock relay board with no ground jumper. I use the front/right terminal on the F.I. socket. ( front right being closest to driver and engine ). Mike, this is a bit odd. Same weekend. (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif) So, which wire gets the diode? The D+ into the relay board or the keyed 12+ power to the MSD which is shown to be the original coil+ wire? From the diagram on pg 8 of MSD manual it looks like the exciter wire needs to be diode protected so the small amont of voltage will will no longer activate the MSD which has it's own 12v constant power source.
