1) Remove intake and throttle body from manifold.
2) Disconnect all vacuum lines and sensors from it.
3) Unbolt the top plate.
4) Unbolt the manifold and remove along with the IMRC motor and cable.
5) Bolt new manifold on.
6) Bolt new top plate on.
7) Plug one of the vacuum fittings on the manifold
8) Connect brake booster vacuum line, FPR vacuum line, and PCV line to manifold.
9) Extend wires on the IAT sensor and install in the intake tube approximately 6" before the throttle body.
10) Bolt throttle body adapter onto manifold, then bolt the TB to that
11) Reconnect air intake tube.
12) Extend wires from the IMRC plug near rear cylinder to the IMRC actuator on the side of the manifold.
The fpr vacuum is now connected to the "L" at the TB side of the manifold.
This is the IMRC connector on the new manifold:

This was a collaboration of a number of people and I appreciate their help, especially Morgan & Sean @ P2R.
Please don't try this if you can't accept possible issues, I accept no responsibility If you mess up your car.

My IAT solution:
The IAT was on the old manifold, I moved it to the intake since the new manifold does not have a port for it.
Something I forgot about:
Two things, remove the bolt that ties the cable for the butterfly before removing the manifold. I had an anxious moment with my long magnetic Snap-On screwdriver getting it out of the intake runner.
Second the Comptech strut bar had to be elevated about 3/4" to get the old out & new on.
