hooking MSD to my 7, leading ignition
So, i'm hooking up a MSD 6AL box to my RX-7. I have all my wires run, i'm hooking it up to my leading ignition coil. The only wires i do not have run, are the small white wire, which i think is optional, the tach wire, also optional and the Green and Purple trigger wires. Which brings up my question, if you're hooking your MSD box up to just your leading ignition. (i'm not trying to run wasted spark) where do i hook up the Green and Purple trigger wires?
Thanks,
Crispin.

These are the most complete instructions I have found for wiring up the MSD. The purple and green wires run to the wires in the dizzy for the leading igniter. Which goes to which is in the links.

Green/purple wires go to the leading ignitor C and B tabs IIRC. Trace the dizzy wires, should be
red and green. Remember "Christmas" (I tend to forget what wire goes where while walking to
the car), and hook the RED dizzy wire to the GREEN msd (red and green... christmas colors). The
green hooks to the purple, and viola.
White wire is optional. I hooked mine to a switched ground, so I can crank the car with no
ignition.
EDIT: Gut the ignitor for the J109 dizzy, or use the stock wire from the points dizzy.
