Jason:
There are any number of ways to wire/plumb the accusump. With an electric solenoid it can be run from a switch on the dash and set either always hot so you can switch it on any time or powered from the run side of the ignition switch so you have to turn the key before you hit the switch to open the solenoid.
Once the accusump has pre-lubed your system you can either leave it on so you have some protection in the event of low
oil pressure while running (hard cornering, stops, acceleration) or turn it off so it will refill and be ready for the next start. Depends on if you want it for just pre-lubing or for constant
oil pressure maintenance. (the electric solenoid will allow the accusump to refill to the engine
oil pressure level even when off but won't discharge into the engine unless it's open).
