2007 impala lock wire

In more detail:

Wire: ORANGE / Black at 24-pin Gray plug at the BCM.  The BCM has 3 plugs, a 24-pin pink plug, 24-pin gray plug, and 16 pin gray plug.

To LOCK: You ground the ORANGE / black wire with a 470ohm resistor.

To UNLOCK: You ground the ORANGE / black wire directly to ground.

TIP:  If you don't want to connect wires up at the BCM since it's tight and messy up there,  you can run 2 wires into the driver's or passenger door and perform the wiring hook up in there on the ORANGE / black wire.

Oh, that wiring is for up to 2006, I guess you have a 2007 so it could be different.  Maybe there's 2 wires that you ground to lock/unlock?  Did you find 2 wires?  Let us know what the solution is when you've found out, I'm sure everyone would benefit from it.

Good luck!

Thanks for the info, I found two orange w/black wire, they were negative trigger.
