Recently bought a Bally Corvette game and I was either too excited to notice, or this happened in the 8 hour road trip home...I had no lights in pop bumpers and when I looked under the playfield, 3 pairs of wires dangling. I can see one of the pop bumpers has two light socket wires coming thru pop bumpers but can't see the others yet. The bulbs are the "blade" style._

Any help or pictures would be greatly appreciated. Both wires go to one side?? find a ground for the other side??

Thank you in advance for your help. Schematics on order but don't want to wait that long and not sure if I am good enough to decipher the schematics at this date.
