Automotive Fuse Help!?

I want to hookup a device to my car that uses 30 amps.

The device needs to come on when I turn on my car, and turn off when I turn off my car.
I don’t want a toggle switch because I might forget it on and it will drain the battery.

I was told I could hook up the 30amp device to my windshied wiper wiring. However, the windshield wiper fuse is much smaller in amps.

I am hooking up two hydrogen generators that use 15 amps each (total 30 amps)
Any suggestions?
