Module body well grounded either through the screw holes or the backing aluminum.
12v at the coil pos and module pos both.
No idea what the ohms on the procomp is, but a 1v or so DC signal is needed.
That is exactly how it is wired. I even ran a groynd wire from heat sink block to ground stud. Just tried another coil this one epoxy flame thrower 1.5 ohm. And still no spark.
