OnStar Fix

First you want to remove the locking clip by prying back the locks on each side to release the lock.
​

Second pull up on the retaining clip on Pins 11 & 12, one at a time then pull the pin out but pulling the wire.
​

Third reverse the white and gray wires, push the pins back in till you hear a click.
​

Forth push the lock back down till you hear two clicks.
​

Finally reinstall cable.
