2001 Powerstroke DTC P1249

I just pulled this code P1249Wastegate Fail Steady State Test . I have the wiring assy, on order which is the pressure hoses that go from the (red) accuator to the manifold to the (some electronic thing) and (green hose) that goes from the electronic thing to the air intake. I pulled vacuum on the accuator and it held, if any of you have seen this code before and you tell what your fix was? I don't get the pressure/vacuum hose (wire assy) until Wednesday after work. The part I ordered was F81Z-9E498-DA

Thanks guys!
