Check out msd's web site the wiring diagram is on there.

The small red wire gets a key hot. Make sure it stays hot while cranking.

Use a multimeter and go through the mess of wires that is no longer being used and find one that has 12+ volts with the key turned on and 0 volt with key off. As stated above make sure it keeps 12+ volts when the key is turned to start. Dont use a test light they only show that you have power not the amount of voltage.

Putting it on the coil doesnt work on msd. The + side of the coil is the trigger side so the voltage is not constant.

Look for a red wire with a light green stripe that went to the original coil my wiring diagram shows it hot with the key in rum/start. Dont know if it will be with the computer gone.
