Can any one tell me what this wiring harness does?

Please. Im at the end of my rope. Im trying to get to the bottom of my random no start condition. I noticed when I wiggle this wiring harness the car dies. can any one please be my hero and tell me what this harness is for, what it does and if weather or not if its defective, can cause this living nightmare Ive been going through for the last two months. its directly in front of the computer, 1995 lt1.

Easy. It's C105. http://shbox.com/1/fan_switch_wires.jpg

The pink wire in it is power for injectors 1,4,6,7. Tan goes to the DLC (should not cause it to die).

Yeah, it does if you are separating the engine harness from the chassis.

Ah, I have never gone that route.

I guess the 'bottom droppers' usually do that?
