On the passenger side of the steering column.
The btsi power does come from the brake fuse, then to the relay which is engergized when the key is on and the transmission is in park. It does not matter if the engine is running or not. That's why I was wondering if the ignition switch was correctly adjusted. The green/white wire should have power in park with the engine running or not. If it does not, check to see if the turn signals work with the engine running.
