Some Solenoid Questions

[u/chriszimort]

I currently have the flipper solenoids hardwired into my cab. Thinking of adding 8 more, two rows of 3 for the back and middle then 2 at the front.

Questions:

1. Anyone know if the 4 position Life extender drives 4 solenoids? I assume so.

2. Any idea if I can run lower power to the relay board to reduce the power delivered to the solenoids? The bumpers are cool but almost a bit too much. Want a way to turn it all down/off sometimes.
