In the "Dr's Guide to Optimizing your Ignition System" they have a
chapter on doing this and the mopar to gm adaptation.
  Off the top of my head ya just wire the pickup coil to the two
"normal" pickup pins of the gm.  It does matter which lead goes to
which pin (the most initial advance being correct).
