1992 Idle Air Connector Wire Colors

I have a 1992 Corvette LT-1 that the Idle Air Control Valve connector got all busted up. I have a new connector but I do not know where each wire goes. There is a Blue/white Blue/black Green/white and Green/black wire in the harness. Can anyone please look at there connector and tell me what position each wire is in? Your help is so appreciated since the local Austin Henna dealership would not help! They said they dont have access to that info! Go figure!! Thanks guys.

I have a book at home that might show the correct colors.. I would need to check
Thanks Jeff, I appreciate the help. I cant wait to get my vette back on the road!
See if these colors match up (from a 1996 Manual)

Connector = Color Wire

A = LT GRN/BLK
B = LT GRN/WHT
C = LT BLU/BLK
D = LT BLU/WHT
I have a '92 service manual which shows. :surprised

A --- LT BLU/WHT
B --- LT BLU/BLK
C --- LT GRN/WHT
D --- LT GRN/BLK

the connector should be marked look closer at it
I'll look at mine tomorrow afternoon and post again.
Here is a photo. LT BLU/WHT is hidden. Hope it helps. I didn't notice a A B C D markings.

I looked at the connector and it is stamped abcd, so along with the photo I think I will have this thing licked!! :partyon: Thanks for everyones help, I couldnt have done it without yall!!

OK, just replaced the connector and a new Idle Air Control Valve. My Vette runs like a dream again. Idles perfectly again. I didnt tell yall that the engine was shutting off while driving and starting back up (6 spd) at 60 70 mph. Then sometimes shutting down and not starting for a few hours or more. IAC was all gunked up. Thanks for all the help! :D
