The ECM is located under the right hand side of the instrument panel.
I do believe on your model the ECM is located under the right hand of the instrument panel. If you really need to remove the ECM I would likely suggest a Haynes repair manual for this operation.
PULL THE UNDER DASH COVER ON THE RIGHT SIDE DOWN AND THE ECM IS LOCATED TOWARDS THE FIREWALL IN A VERTICAL POSITION. YOU WILL SEE THE ECM WIRING CONNECTORS ( I THINK THERE ARE THREE WIRING CONNECTORS) GOING UP TO THE ECM.

To access the ECM (Engine Control Module) on a 1994 Buick Regal 3.8, first, disconnect the negative battery terminal to ensure safety. Then, locate the ECM, which is typically found under the dashboard on the driver's side, near the steering column or behind the glove box. You may need to remove some panels or the glove box for better access. Once located, you can unplug the connectors to diagnose or replace the ECM as needed.
