Can anyone tell me where I can run a switched power source from my fuse box that is switched on when the key is on and not constant?

NM I figured it out.

 

Windshield wipers and power windows just to start. Get a cheap test light and find the one you want by testing key-on and key-off. What are you tapping into those for?

 

I can't get my raptor pump to run off the plug it plugs into. It will run for a second and shut off. If I run it straight to the battery it runs fine.

So I was going to run it to a switched power source

 

Does it run for a second then shut off when you turn the key to on? Because that is usually just the pump building up to pressure and shutting off

 

It will prime like normal and then shut off after the truck runs for a few minutes. So at first I ran the power to the battery through a fuse-able link. It would run a few minutes and then blow the fuse. So I just ran it straight to a power source and it stays on.
