Default AEM install

Could someone please help me with the correct placement of the vacuum hoses on the AEM CAI. My check engine light just came on, and I am concerned about engine damage. I have already looked at all the pics about the topic, and none of them show the proper routing of the hoses. Please help!

Facing the car:
The large vacuum tubes are pretty straight forward. The smaller ones are easy to mix up:

The one with the check valve (1/8" exiting frame crossmember left) goes to the upper fitting under the injection manifold. The 1/8" coming off the lower injection manifold fitting goes to the fitting on the solenoid air valve nearest the AEM pipe (the fittings on the solenoid air valve should be facing the rear of the car if properly installed). The one farther away from the pipe (no check valve) goes down to the right side crossmember (opposite the 1/8"with the check valve).

NOTE: For whatever reason the 1/8" hose from the lower manifold fitting to the solenoid fitting nearest the tube is not the right size (hose is too big or fitting is too small (?). The 1/8" vacuum tube may come off the solenoid air valve or be loose at this location. This will result in a light in the cockpit. Try a zippy tie or a softer 1/8" tube if this fitting feels loose to you.

Any questions call feel free to PM me for my phone number.
