here's the pinout for the cobalt SWC
the horn twist-lock connector is going to be your power source for the steering wheel. this needs to be tied into the red harness thats built into the wheel (for the horn obviously) and also needs to be connected to the WHITE/ black wire that is the 12V reference for the cobalt controls.
-C (pink) not used, left switch
-D (grey) not used, left switch
-E (D-blu) this gets connected to the PAC SWI-JACK or similar SWC interface
-F (white/black) gets connected to the 12V power connector for the horn
-G (grey) this is connected to park lamp supply voltage (illumination for the switches.. does not have to be hooked up)
-H (dk grn/ white) not used, left switch
-J (tan) not used, horn connector (removed when re-wiring power source)
-K (black/white) gets connected to ground source on the steering wheel
comparison of the airbag connectors. the older style is on the left, the newer style is on the right.
to make your life easy, pop the yellow top off and grind it down with a dremel or a file. I already tried swapping the yellow tops between the connectors, but they are keyed so that doesn't work, you need to grind it down to fit.
there is one issue with the sunfire clockspring.
as you can see, the hole for the steering wheel power puts the wires in a position where it will NOT clear the cobalt steering wheel. There is not enough of a leg there to cut away in order to clear the wires from the sunfire clockspring, so I decided to drill a new hole in the clockspring in order to position the wires in a place where it would fit through the wheel.
the clockspring has about 7 turns from lock to lock, and our steering wheel only goes about 3.5, so turning the clockspring the little bit needed (about 45 degrees) will not hurt the function of the clockspring.
herre it is installed after drilling the hole.
I'm going to post the wiring diagram and parts list a bit later tonight.
