The stock mopar ignition has two separate voltages for the ignition system....they are start and run systems... have some one move the key to start and with a volt meter or a test light....find the wire that has 12 volts...that is the start side...release the key to the run position...the start voltage will disappear and then the other wire is get the voltage...connect those two wires together...and then connect them to the small red wire that goes to the msd 6...that red wire needs 12 volts to run and start...it is basically turns the msd on and off......the heavy red wire provides the voltage for the msd...
