im having a hard time with one of the steps.. specifically the second part of this one: Connect the SWI-PS 's Green wire to pin 11 (dk. blue) in connector 1 of the above connector. Connect pin 14 (white/black) in connector 2 to +12v accessory. im installing this on an 07 cobalt SS.. now im guessing i have to tap pin 14 to a 12v acc wire correct? does it have to be constant or switched? and also, i have to use the gmos lan 4 harness if it matters. this just doesnt make any sense to me because your not tapping the 12v into the pac module so how is it going to work?

I am interested in any reply becasue I have the PAC unit. Thanks.

12v ACC is switched, when the vehicle turns on, aka Red wire off the GMOS harness. and IIRC the PAC module should have it's own power wires as well.

ok, i have one more question.. im almost done wiring the harness and i have 2 more wire on the gmos harness to connect.. the parking brake wire and the reverse wire. now im guessing i have to tap those from the gmos harness to the avic's harness and then run them normally? im going to ground the parking brake wire obviously, i just dont know if this is the way its supposed to be done. thanks : )
