So, any electrical geniuses on here?
Here is what I want to do. The OM617 is turned off by vacuum. I would like to have the vacuum pump turn on for about 20 seconds after I turn off the ignition switch and apply vacuum to the injection pump of the OM617. I guess there is probably a relay out there that could do this. The power on my trucks accessories turns off after I open the door. If I could do something similar, that switches on after the ignition is shut off. Any ideas?
