Thanks guys! Yes--I did the do, and the one goes to the 1000 points, the other is power.
THE FRONT is the ground, btw, so it first hits the lights/bonus tied on one, and then they get power and do everything needed. Front and back have single wires for power and ground, the middle is double tethered wires for bonus and lights.
I reversed two of them on my last switch by accident, but it does duty just as well. I fine tuned them to be more "feather touch" and they work properly now.
The new faces are invigorating.
This KING KOOL is shaping up nicely. Just need to fine tune the 10-point relay better, make new plastics above the field, get my new backglass in the mail, and it's all about the playfield being touched up. The advice here is right-on--I even repaired a shoddy 4000 bonus light today by welding the power to the nipple.
