I got my F90bt the other day. I drive an 08 Cobalt SS with onstar and premium sound so I got the gmos-04 wiring harness. Also i got a pac swi-ps steering wheel control adapter. So heres what I need to know:

1.) Do all the colors on the wires that come with the unit match the gmos-04 wiring harness?

2.) Can someone explain or link me to the pac swi-ps install caz i need major help with that?

3.) Where do I find the pink speed wire in the cobalt?

I think i understand the hardwire bypass already so I'm good with that but would appreciate help. Thanks guys.

anyone any help is appreciated. im very new to this. this will be my first install.

VSS = Yellow at the ECM under the hood. Connector 2 Pin 18

All the wire colors "should" match up with the AVIC Harness. Read the instructions that came with the GMos-04 to see what each wire is supposed to do...
