What's missing from my harness?

My harness was apparently removed from the donor car with an axe. I've identified most of the connectors that'll need to be repaired/replaced, but I'm not sure what went here (circled). There's about 15 wires in there, so it's likely somewhat important.

Anybody know what went there off the top of their head?

That looks like the segment that goes to the under-dash connectors. It routes down the pax side fenderwell and meets up in the passenger footwell under the dashboard.

This would explain why they chopped it I suppose. Look up connectors C220 and C230 and see if the colors match up w/ the ends you see cut.

Thanks, Crainholio.

Confirmed that it was C220 and C230 that were cut.

Short of getting someone to chop up their engine harness, where would one get replacement connectors? (preferably with pigtails since I don't know how much of the length was cut)

The Helms manual gave an eight digit number for each of them, but GMPartsDirect doesn't recognize as a valid part number.

Connectors
 

Ouch, at least that was the only damage.
This web site might have what you need, http://currentperformance.com and go to the OEM connectors link.
Hope this helps,
