Not exactly a stereo question but you guys probably know wiring.

I'm trying to run my dual fuel pumps in tank. I need to find a key on source somewhere in the car that I can tap into and can handle 2 20amp I line fuses and be alright. I'm not much on wiring but I seen the ignition 12v on the fuse panel above the drivers kick plate. Would that carry that much power?? Can't start car until I find power source... Help.

 

There is no existing ignition switched circuit in the car that can handle an additional 20 amp load so do not try to tap into any existing circuit.

The best way to do this is to run a new large gauge wire (with appropriate fuse) to the battery for your power supply and then use a relay connected to an ignition switched circuit to turn the power on and off.
