    I ment at the harness but sparky cleared this up for me in another post, thank you for that tho. It seams in the harness its only data sigs and not a positive or negative sig till it goes through the board on the cluster. I dont want the stash a cluster behind my dash just to tap 2 lights.

    On my 06 Cobalt 2.4L prints it is C1-12 Brn/Wht #419 and computer grounds the light (as shown in your drawing). There is also a logic signal that goes on the serial bus. I hope it does because I am wiring it that way.
    On the 06 Cobalt 2.0L Vin P it is C1-40 Brn/Wht #419 and computer grounds the light same as you show. So if your motor is Vin P and you have a C1-40 Brn/Wht it should be your MIL Cntrl. Logically.
