Here is a good "how to" on using the Toyota electric PS pump:

The writer just leaves the pump running. At idle (car sitting still, VSS not connected) it draws 4A, draws about/under 40A at full load (sharp turn to lock). Toyota uses a 50A relay, writer has had no issues using a common 40A. It may draw right at 40A at full lock, but doesn't stay long enough to burn out/damage the relay... or hasn't for this guy. He's running it in an EV.

PROSTOCKTOM -- this is just a PS pump, not full electric steering. Still a standard PS rack (or steering box). Just replaces the engine driven hydraulic pump.
