In my experience, the diy'er with an uncut 20v wiring harness does better than the one that is trying to work with a cut harness. Check out the padandwheels blacktop wiring writeups. They are a great BT wiring reference for someone with an uncut harness....although I take a different approach to wiring the 20v, because I have to do both cut and uncut.

On the AC, with the 16v clutch, it's basically 1 magnetic clutch control wire. It runs from the grey strut tower plug to the A/C. It's very easy to keep a working 16v compressor. Using the 20v compressor is a bit of a problem.

Taking a look under the oil cap, or getting the photo, is the first thing people should do when buying a motor. Most broken external stuff is cheap to replace and forgivable, for example you can probably replace your airbox for $50. It's getting a sludgy motor that turns what should be a $1500 project into a $2500+ project.

Check out club4ag for a replacement box. Most of the rwd corolla guys have no use for the box as it points the wrong direction.
