Toyota MR2 electric steering pump

I have bought a Toyota MR2 Spyder steering pump. I am looking for information for the second gen, (integrated control module) pump.

I have installed and connected the MR2 pump. I have the second gen, so the wiring was a little different than the links I found, but no problems. The pump automatically runs slow drawing no more than 5 amps when idle and 15 -20 during dramatic turning at stop. I highly recommend this method to anyone building an electric car. a local hydraulics shop was able to fabricate the adaptor hoses for fairly cheap. <$100.00.

what kind of price should one expect for the toyota steering pump ?
