Is the start signal neccessary? on a l28et stock efi

Well I fixed my ecu problem. But in the process of "checking my connections" I cut my entire #2 plug off. I am unable to tell what solid wire is for the a/c and what wire is for my start signal. If anybody knows a way to trace it or what plug left, middle, or right on the ecu it would be greatly appreciated?

 

The real question is it absolutely necessary to have the start signal? I know the ecu makes the car run really rich for the first 30 seconds. But if one was to not hook it up would the car not want to start? Thanks.

I tested what difference it actually made when I wired my car a few weeks ago. Pretty much as far as I can tell, the car will start after about 1 second and a handful of revolutions with it connected. With it disconnected it will take about 2-3 seconds to start.

 

So it's basically with it - one twitch of the key, with it disconnected you have to hold it a bit.
