going back to your parts list a sec.......

you have a coi8-u10 & coi4-u10 not a col (no such animal).

depending on what slots have what boards determines where port 1 is. i'll guess that your system is laid out like this:
slots card
1 coi8
2 coi4
3 esi8
4 esi8
5 esi8
6 esi8
7 esi8
8 vms4

if this is the case my guess would be that port 1 is on yellow/blue pair in amp cable #1.
