Its the RED conector,You will need to get a pin from a old harness or order a new one. Were do you live ? I have a few with a bout 6" of wire on it from a old harness ,you can just sorder a longer wire to it. That is what i done and it work perfect.

Pins are like 50 cents from eficonnection dot com or something similiar...sure a google would find it.
Remove the connector, punch a hole in the yellow rubber,
Insert pin and you will feel it snap into place. Reinstall connector.

Joey, the wiring works great, LOL the tuner is what needs help 
The COS 5 I have pulling the timing perfectly when active, the VE Multiplier I have not seen work. I am using a rocker for turning it off and on.
The Purple Grey and Black wires on my pic I inserted to the EGR PCM Pins, it is my 5V power source for my sending unit (Fuel Pressure) and ground as well. The Purple wire is tha voltage for the Fuel Pressure PID through the EGR. The lone Black wire is the COS5 (goes to a rocker for ground).

I just setup COS 5 on my car last week, just have to wire it up when I get the spray back on it, gonna have it go off a relay that's tripped from my nitrous arming switch so I don't have to worry about flipping any other switches!
