Where to Find 12V Power Under the Hood (Drivers Side)?

The underhood fuse box is right there. It's a great place to stash a SPDT/SPST relay for your pump. You'll use battery power for the pump itself and use a tiny amount of power (250 mA or so) from whatever control circuit you desire to energize the relay.

That's how I'd do it. Otherwise, for a straight circuit power source, perhaps you don't use an OEM circuit anymore and can pirate from it. Here's a diagram (courtesy of S&2B's [site host] and TMoss [diagram author])

Good luck.
