It's actually called the EGS. It should be located near the engine computerwhich sits under the hood at the firewall.

There's a small black box in the engine bay on the driver's side. There are 4 screws that you need to remove. The EGS is blue.

It is located in the E-box. There is the DME and EGS computers in there along with several telays and fuses.
