rev limiter with dodge electronic ignition

I've been trying to run an MSD Soft Touch rev limiter with a chrome box Mopar ign. Hooked it up as MSD instructions but will not work. Could you possibly give me a link to the electrical hookup. Are you using the white or purple wire for the hookup ? Thanks in advance, Keith.



soft touch =

red , to red at ecu - splice into it

black to ground

green and white both to coil negative side
