Urgent help needed. Stranded at work.

Suddenly the car will not start. It feels like that the neutral safety switch is not on. As I turn the key I hear a faint click and nothing.
More detail: I parked right next to the building where I work (one of the prime 6am spots) this morning. I sneaked out during lunch time trying to fix my radio (connectivity problem somewhere in the back). Instead of move the car to a remote spot where I normally do some light work on my car during lunch break, I decided to just do it right there. I thought that I’ll be done in no time, just pulling the radio out and check the wiring in the back. I turned out the metal tab in the back of the radio stuck and I managed to get the radio out in over 30 min. It was hot out in the sun and I have to run the AC while I was struggling with the radio. After the radio is out, I tried to disconnect and re-connect the wiring in the back. Suddenly, the motor shaked hard for a few seconds and died. When I tried to re-start it, it won’t do anything.

I do have access to a multimeter here. However, I don’t have my green wiring book with me. And keep in mind, I would not want to keep the hood popped up too long there since all my colleagues will happens to walk by and you know what I mean.

The question is: if I put the key at position 2 (running position), can I start the car by using the test wire (the one you use to bump the motor)? This is to assume that car is “startable”. If the answer is yes, where is that pigtail? I just want to move the car far away from the building first. Or, am I better off just call AAA to tow it to my house? Sorry, I know it’s pretty embarrassing! Thanks
