1990 Mirage ECU location?

My buddy has a 1990 Mirage and cannot find the ECU in the Haynes manual or in the car for that matter? He found the tranny computer under the dash.

HELP!

Thanks

The ECU is on passanger side under the dash, to the right of the glove box. 2 bolts hold it in . Only need to remove the plastic plate at the foot level to get to it.
