Thanks for the pics, that's very helpful. So if I'm seeing this right, one of the power steering lines and one of the A/C idle up lines each run to the actuator. Right now my power steering runs from right before the throttle plate and returns on the manifold with no other devices involved.

Anyone have a spare they want too part with (actuator)? Dealer probably wants $300 for one.

Thanks a lot for those pics.
