Carb swap into my 95 gt. Wiring issue?

http://sn95forums.com/showthread.php?25460-EFI-to-Carb-conversion-Mods-Sticky-please

Im using this write up right here and all the rest of the wiring is accounted for with just a slight color difference on one wire....BUT
heres my issue...

----GROUND #97 (tan/light green - 18ga) to a suitable chassis ground. This creates the ground for the primary side of the fuel pump relay.

For the life of me i can't find this wire in any diagram i look at. I'm using alldata online and my haynes manual as well. i know this write up is for 89-93 foxs and 94-95s have slight difference but i'm stumped on this one wire. Anyone here done this or have insight please? i've searched up and down for it but nothing answers my question. THank you.
