Ive been able to find out it is yellow wire pin 18 on the ecm on 2005

But the diagram i have is for a 2005 and it shows 2 connectors but my 2006 ecm has three conectors was wondering if anyone has a diagram or more info on a 2006 Cobalt ss ecm any help would be appreciated locating vss wire

Ok I cant find 2006 wiring diagrams anywhere and my ECM has 3 connectors J1,J2,J3

There are two wires at the transmission control module, yellow is high OSS, and purple is low OSS.
