the (B) & (C) terminals on one end, the (B) goes to switched 12V. the (C) goes to coil neg primary. The (w) & (G) on the other end go to dist pickup, I forget which polarity. At the ballast, tie the blue and brown (switched 12V) together & run it also to the coil positive primary terminal. Module quality varies greatly, an OE one is good & MAYBE an aftermarket one (no exp there).
