Need help from Toyota 2ZZ-GE owners!

I need help. My codriver and I were working on his Lotus Elise, getting it ready for the final statewide autocross in this weekend. While removing the airbox, we pulled a few wires out of a connector. Unfortunately, we yanked out two wires, so we're having a hard time getting it right (making the connection is a big variable too). I'm going over this weekend to help fix it, but the engine is throwing codes with the wires stuffed in either way. The Lotus wiring diagrams aren't specific enough, so I'm turning to owners of the 2ZZ-GE for help.

The wiring harness is just past the airbox,and it looks like it connects to an Intake Air Temperature Sensor and Mass Airflow Sensor. Specifically, the wires on the LEFT side of the connector are the ones we yanked out. The car is throwing a code for the IAT and went into limp mode.

Assuming two things: Lotus just pushed the engine straight back from a front/front layout in the Celica to a mid/rear in the Elise. The airbox is on the driver's side of the car, the intake manifold is towards the front of the car. We also assume that Lotus didn't make a different wiring harness and just put in their own ECU.

I also think this is the same engine in the Pontiac Vibe GT, Corolla XRS, and Matrix XRS (180hp 1.8L).

So I'm looking for a COLOR PHOTO of the harness going to the MAF/IAT sensor between the airbox and throttle body. There's about 6 wires going into a flat connector. I'm going to use something more solid for the connect (like a paper clip) but we don't want to risk damaging the sensors by getting the wrong polarity. I'd like to positively ID the wires before try again.
