|  Soo... where is this DIS module?  Built into the coil pack base?

DIS module can be about anywhere they want to mount the coils.
Yes, the coils mount to the DIS module.

|  How many wires does a distributor-type wiring harness have running to
| the HEI module?  One?

There are 2 wires that connect the reluctor's pickup coil to the module, and
then 4 wires that run to the ecm, and then the ground wire for the coil.

There are diagrams at the FTP that might better spailn this then I.  The 3.1
Grand Prix Turbo is a 727 using DIS, and the 90 Fbody (Dissy) wiring is a
730.
