Almost sure it's behind the glove box, two electrical connectors attached to it. a 16 pin and 24 pin connector .12 wires in each connector.

Be advised that the blinking light is a "flash out code" that is telling you the fault if you count the blinks. It's a 2 digit number. It will blink in sequence. If you count it and post the number, I can help give you some direction to be prepared when you get a diagnosis and repair performed. The module is typically not the cause of failure. Just reading your concern, my initial thought is a 3-2 with a sliding contact (clockspring) failure.
