Quoted from Pinballerchef:Hmmm....I looked into the "CFTBL MOD" for the pops but it was more like just connecting them to the lightning bolt flasher inserts in the middle of the pops....doesn't seem to coincide with GORGAR. Maybe Tmezel can figure something out....if so I'm a buyer for the MOD for my GORGAR.

It shows how to connect a new flashbulb and tie it to the coil on the pop bumper. CFTBL comes with no lamps in the pops, the mod is to put small 5V or 12V flashbulbs into the pop bumpers rather than just adding GI lamps. There is an individual lamp in each pop bumper that goes off when the bumper bumps.
Wiring it for Gorgar would be almost identical. You can even tie all 3 pop bumpers to cause the single flashlamp to go off when any of the pop bumpers are hit. (same as in the instructions only instead of wiring an individual lamp to each coil, wire the same lamp to all 3 coils using a diode for each)
