I think I have the timer wiring figured out thanks to Jason at WM...

My next question is where to draw the power from. I will have 4 jabsco pumps and 4 timer modules in all. Should I use the existing circuit block as 08LSV did here?

Great write up BTW!
Using the pump side to power the pumps and solenoid side to power the switch? That would still still leave me a pump short... Or should I run some sort of distro block back to power all of the pumps?
I am also looking for some plugs so I could unhook and remove the pumps to service the impellers... I dont have much 12V wiring experience at all so am looking for ideas. Thanks!
