a Frenchman who needs advice for GM HEI MODULE!!!!

If you mean the positive and negative of the 2 pickup wires, what I did was to shine a clamp-on timing lamp at the distributor reluctor and verify the teeth aligned with the pickup when the lamp flashed. Easiest to spin the distributor rotor off-engine by hand. Since the cap is off for this test, connect the HV lead off the coil tower to gnd (or to a spark tester). I think I wrote down the GM wire colors and which pin of the dbl-bullet connector they go to for correct polarity. If wrong polarity, you will still get sparks, but much more erratic since triggered off an inexact point between the reluctor teeth.
